OPINION
WILLIAMS, Circuit Judge:
Elizabeth Brinkley appeals the grant of summary judgment in favor of her former employer, Harbour Recreation Club (HRC), on her Title VII, 42 U.S.C.A. §. 2000e-2(a)(l) (West 1994), and Equal Pay Act, 29 U.S.C.A. § 206(d) (West 1998), claims. Brinkley, who was general manager (GM) of HRC, argues that she created a [603]*603genuine issue of material fact on her Title VII claim when she put forth evidence that demonstrated that some of her superiors on the HRC Board of Trustees (Board) favored her termination because they lamented the loss of a particular greens superintendent who had publicly stated that he - was not pleased to work for a woman. Brinkley also • asserts that the district court made two errors in addressing her Equal Pay Act claim. First, she alleges that the district court based its summary judgment ruling on an affirmative defense that was improperly raised. Second, she contends that the district court erred when it granted summary judgment to HRC on the basis that HRC had established the “faetor-other-than-sex” defense, 29 U.S.C.A. § 206(d)(l)(iv), because HRC had produced insufficient evidence that such a factor motivated HRC’s decision to pay her male successor a higher salary. Because we determine that summary judgment was appropriate, we affirm.1
I.
These facts, drawn from Brinkley’s pleadings, affidavits, and depositions, are expressed in the light most favorable to her as the non-moving party. See Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 255, 106 S.Ct. 2505, 91 L.Ed.2d 202 (1986) (stating that an appellate court reviewing a grant of summary judgment is required to view the facts in the light most favorable to the non-moving party and must draw all reasonable inferences there-' from).
In October 1993, a group of homeowners in the Fairfield Harbour development in New Bern, North Carolina, having purchased their residential community’s country club during Chapter 11 bankruptcy proceedings, organized HRC as a member-owned club. The officers of the HRC Board hired Brinkley to be the club’s business manager on October '7, 1993. Brinkley possessed a bachelor’s degree in business administration from Ithaca College, but at the time she took the position as HRC’s business manager, she had no previous country club experience.2 Brinkley received a starting salary of $30,000. Her duties as business manager included: setting up and supervising the business office; organizing and maintaining membership records; coordinating insurance coverages; implementing contracts; maintaining corporate documents such as bylaws; assisting the Board in establishing budgets; supervising accounting, record-keeping, and reporting procedures; communicating with members; and selecting and maintaining a computerized point-of-sale system.3
In January 1995, after a vote by the HRC Board, Brinkley was promoted to the position of GM of HRC. Shortly before they voted. on promoting Brinkley, members of the Board discussed during a meet[604]*604ing with the club staff the possibility of promoting Brinkley to GM. Board members asked the staff whether anyone would have difficulty working with Brinkley in that capacity. One staff member, Dick Brandel, the greens superintendent, stated that he wasn’t sure he could work for a woman.
HRC and Brinkley entered into an employment contract prepared by Brinkley on February 16, 1995. The initial term of the contract was three years and. provided that her starting salary was $50,000.4 Brinkley was eligible for cost-of-living increases as well as merit raises over the term of the contract.5 Further, the contract provided that a two-thirds majority of the Board could vote to terminate Brinkley without cause. In the event of such an occurrence, the Board would be obligated to pay Brinkley for the remainder of the contract term. If, however, a two-thirds majority of the Board determined that Brinkley was guilty of fraud and abuse in the performance of her duties or of gross negligence, the employment contract could be terminated immediately.
At the end of Brinkley’s first year as GM, the club had lost $166,111. At the same time, the Board became, concerned about the poor working relationship that had developed between Brinkley and Brandel, the greens superintendent. Brinkley and Brandel became embroiled in a dispute regarding expenses Brandel had incurred. Brinkley concluded that Bran-del had incurred unauthorized personal expenses and requested that he reimburse HRC. Brandel refused to reimburse HRC; Brinkley considered the refusal to be an act of insubordination and requested that the Board support Brandel’s termination. A majority of the Board did not support Brandéis termination. Instead, the Board altered the reporting relationship between Brandel and Brinkley. After the Board’s vote, Brinkley and Brandel were instructed that henceforth Brandel was to report to the golf pro rather than to Brinkley. Additional concerns over her job performance arose among members of the Board when Brinkley led a membership forum meeting in February 1996 during which the Board members concluded that Brinkley had made inappropriate comments about HRC’s management and her relationship with the Board.
Dick Brandel eventually resigned from HRC in May of 1996. Later, Brinkley was informed that “you did not win with Dick Brandel leaving.” (J.A. at 393.) Also in May, a Board member circulated a memorandum proposing that golf operations be made a separate autonomous operation headed by the director of golf and suggesting that Brinkley be demoted back to the position of business manager. Although this plan was never formally implemented, on June 5, 1996, Brinkley was instructed “not to micro manage golf.” (J.A. at 393-94). A few days later, during a discussion with the golf pro, Brinkley expressed her anger with the fact that the golf pro had been communicating directly with the Board. Brinkley complained that this behavior was undermining her authority as GM. At the conclusion of their meeting Brinkley said, “If this [is] the way you’re going to do it, you can sink or swim on your own.” (J.A. at 37.)
On June 11,1996, the Board had a meeting with the golf pro. After the meeting, representatives of the Board approached Brinkley and told her that they would have to abide by her decision to relinquish management of the golf operation on a temporary basis, but that the Board wanted a cohesive management team and was disturbed by the division of management. After considering their options, the Board informed Brinkley that her employment contract for the GM position would not be renewed as a result of her decision to give up managing HRC’s golf operation. On July 9, 1996, the Board proposed that [605]*605Brinkley continue at HRC as restaurant manager. On July 11, 1996, Brinkley informed that Board that she would not accept the position of restaurant manager.
Nevertheless, the Board decided to hire' someone new to take over management of HRC. After an interview on July 13,1996, James Paschal, who had eleven years of country club management experience, was hired to take on the position of chief operating officer6 (COO) on a'temporary, ninety-day basis while the Board decided how to proceed. On July 19, 1996, Paschal signed a ninety-day contract providing that his salary would be $1,200 per week plus free meal privileges.7 This salary represented a mutually agreeable temporary arrangement based upon what the Board felt it could afford.
Prior to the termination of his ninety-day contract, the Board decided to hire Paschal as the permanent COO. On September 1, 1996, Paschal and HRC entered into a contract that provided for a salary of $75,400 per year. Under the contract, Paschal’s free meal privileges continued. Additionally, the contract provided that Paschal would be compensated in the amount of $300 per month as an automobile allowance. The Board determined that $75,400 would be an appropriate salary on the basis of Paschal’s prior salary history and information it sought from the Country Club Managers Association regarding the average salary figures at similar-sized clubs. At about the same time, on August 30, 1996, Brinkley took three weeks of vacation at the direction of Paschal. Upon her return, on September 23, 1996, the Board terminated Brinkley’s employment contract for cause. The Board determined by a unanimous vote that Brinkley had been grossly negligent in the performance of her duties. Specifically, the Board noted that Brinkley unilaterally had terminated her management of the golf 'Operation, had exercised poor judgment handling two problematic contracts, had failed to consult with the Board over personnel matters, had promoted an unqualified employee to the position of restaurant manager, had given misinformation regarding a capital equipment purchase', and had publicly aired her opinion that she did not agree with Board policy to HRC members.
II.
As a result of the foregoing events, Brinkley filed a written charge with the EEOC claiming that she had been demoted, terminated, and otherwise discriminated against on the basis of sex. After receiving a right-to-sue letter, Brinkley filed suit in the United States District Court for the Eastern District of North Carolina. In her complaint, Brinkley made three claims for relief. First, Brinkley claimed that her termination from HRC was the, result of discrimination on the basis of sex, a violation of Title VII. 42 U.S.C.A. § 2000e — 2(a)(1) (West 1994). In her second claim, Brinkley alleged that HRC hired a male, as COO to perform identical duties to those that she had performed as GM and paid him a, higher salary in violation of the Equal Pay Act. 29 U.S.C.A. § 206(d) (West 1998). Finally, Brinkley averred that her termination was a result of HRC’s breach of her employment contract.
After undertaking discovery, the parties filed cross-motions for summary judgment. The district court denied Brinkley’s motion for summary judgment and granted HRC’s. As a result, the district court also dismissed without prejudice the breach of contract claim over which it had taken [606]*606supplemental jurisdiction. In granting HRC’s summary judgment motion, the district court reasoned that Brinkley had failed to establish a prima facie case of discrimination under Title VII. Specifically, the district court held that Brinkley had not met her burden of proving that she was replaced by a man with comparable qualifications because HRC had established that Paschal had significant prior experience in .country club management lacked by Brinkley. Additionally, the district court concluded that Brinkley had not been performing her job as GM at a level that met the Board’s expectations. The district court also concluded that summary judgment was appropriate on Brinkley’s Equal Pay Act claim because HRC had proven an affirmative defense under the Act, ie., that the pay differential was based upon a “factor other than sex.” Specifically, the district court determined that HRC had presented adequate evidence to show that Paschal’s superior experience and salary history, neither a factor related to sex, accounted for the pay differential between Brinkley and Paschal. Brinkley filed a timely notice of appeal.
On appeal, Brinkley makes three primary arguments. First, Brinkley asserts that the district court erred when it concluded that she had not made out a prima facie case on her Title VII claim. Next, she claims that the district court erred when it considered HRC’s affirmative defense — that the pay differential between Paschal and Brinkley was based upon a “factor other than sex” — because that affirmative defense was not properly raised in HRC’s answer, but rather was first raised in HRC’s summary judgment motion in violation of Rule.8 of the Federal Rules of Civil Procedure. In the alternative, Brinkley maintains that the district court erred in granting summary judgment to HRC on the Equal Pay Act claim because, even if the affirmative defense was properly raised, the evidence put forth by HRC was insufficient to establish the defense by a preponderance of the evidence.
We review de novo the district court’s decision to grant HRC summary judgment. See Higgins v. E.I. DuPont de Nemours & Co., 863 F.2d 1162, 1167 (4th Cir.1988). Summary judgment is appropriate only “if the pleadings, depositions, answers to interrogatories, and admissions on file, together with the affidavits, if any, show that there is no genuine issue as to any material fact.” Fed.R.Civ.P. 56; Celotex Corp. v. Catrett, 477 U.S. 317, 322, 106 S.Ct. 2548, 91 L.Ed.2d 265 (1986). In deciding whether there is a genuine issue of material fact, the evidence of the non-moving party' is to be believed and all justifiable inferences must be drawn in her favor. See Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 255, 106 S.Ct. 2505, 91 L.Ed.2d 202 (1986). Guided by these principles, we address Brinkley’s arguments that summary judgment was improper se-riatim.
III.
Brinkley first contends that the district court erred when it granted summary judgment on her Title VII claim. Brinkley’s claim in this regard is two-fold. First, she asserts that the district court erred because she had produced sufficient direct and indirect evidence that discrimination led to her demotion and eventual termination from the GM position to establish a prima facie case without applying the McDonnell Douglas presumption. Second, Brinkley asserts that even if she had not produced sufficient direct and indirect evidence of discrimination, then she produced circumstantial evidence sufficient to satisfy the McDonnell Douglas proof scheme. See McDonnell Douglas Corp. v. Green, 411 U.S. 792, 93 S.Ct. 1817, 36 L.Ed.2d 668 (1973). Upon those two bases, Brinkley argues that the district court erred in ruling that she had not established a prima facie case.
A.
There are two avenues of proof by which an aggrieved employee can prove [607]*607a Title VII violation. See Burns v. AAF-McQuay, Inc., 96 F.3d 728, 731 (4th Cir.1996). First, an employee may utilize “ordinary principles of proof using any direct or indirect evidence relevant to and sufficiently probative of the issue.” Tuck v. Henkel Corp., 973 F.2d 371, 374 (4th Cir.1992). To overcome a summary judgment motion based upon this method of proof, the plaintiff “must produce direct evidence of a stated purpose to discriminate and/or [indirect] evidence of sufficient probative force to reflect a genuine issue of material fact.” Goldberg v. B. Green & Co., Inc., 836 F.2d 845, 848 (4th Cir.1988). “What is required is evidence of conduct or statements that both reflect directly the alleged discriminatory attitude and that bear directly on the contested employment decision.” Fuller v. Phipps, 67 F.3d 1137, 1142 (4th Cir.1995). If such evidence is lacking, the plaintiff may nevertheless proceed under McDonnell Douglas. See Tuck, 973 F.2d at 374.
McDonnell Douglas first requires that the plaintiff establish a prima facie case of discrimination by a preponderance of the evidence. See McDonnell Douglas, 411 U.S. at 802, 93 S.Ct. 1817. To establish a prima facie case of discrimination under Title VII, Brinkley must show (1) that she is a member of a protected class; (2) that she suffered an adverse employment action; (3) that at the time of the adverse employment action she was performing at a level that met her employer’s legitimate job expectations; and (4) that the position remained open to or was filled by similarly qualified applicants outside the protected class. See St. Mary’s Honor Center v. Hicks, 509 U.S. 502, 506-07, 113 S.Ct. 2742, 125 L.Ed.2d 407 (1993); Karpel v. Inova Health Sys. Servs., 134 F.3d 1222, 1228 (4th Cir.1998); Williams v. Cerberonics, Inc., 871 F.2d 452, 455 (4th Cir.1989). Once the prima facie case is estabhshed, the burden shifts to the employer to articulate a legitimate, nondiscriminatory reason for the adverse employment action. See Texas Dep’t of Community Affairs v. Burdine, 450 U.S. 248, 254, 101 S.Ct. 1089, 67 L.Ed.2d 207 (1981). If the employer meets its burden of production, the presumption of discrimination raised by the prima facie case is rebutted and “drops from the case,” id. at 255 n. 10, 101 S.Ct. 1089 n. 10, and the-plaintiff bears the ultimate burden of proving that she has been the victim of discrimination, see St. Mary’s Honor Center., 509 U.S. at 507, 113 S.Ct. 2742, 125 L.Ed.2d 407.
B.
Brinkley initially claims that she has put forth sufficient direct and indirect evidence of discrimination to create a genuine issue of material fact to survive summary judgment on her Title VII claim. She points to several pieces ■ of evidence in support of this assertion. First, Brinkley notes that prior to her promotion to the GM position, Brandel, the greens superintendent, a future subordinate, announced that he would have difficulty working ' for a woman. Next, she asserts that Brandel was a very popular and highly valued employee among male members of the Board who eventually made the decision to terminate her. Further, she alleges that because Brandel did not function well under female management, the Board reorganized the reporting relationships so that Brandel would report to the male golf pro. Brinkley also claims that several male members of the Board found her to be blame-worthy for Brandel’s eventual resignation from HRC. Brinkley additionally points to statements in an affidavit from a former club treasurer that indicate that the treasurer believed that a specific male member of the Board had difficulty accepting women’s views if they differed from his own. Finally, Brinkley asserts that her replacement, Paschal, made sexually suggestive comments about another female employee in her presence and also made several stern warnings that Brinkley’s job was in [608]*608jeopardy.8
The evidence Brinkley catalogs is not sufficiently probative to raise a genuine issue of material fact on the issue of whether the Board harbored discriminatory animus that resulted in Brinkley’s demotion and termination. To survive summary judgment on the basis of direct and indirect evidence, Brinkley must produce evidence that clearly indicates a discriminatory attitude at the workplace and must illustrate a nexus between that negative attitude and the employment action. See Fuller, 67 F.3d at 1142; EEOC v. Clay Printing, 955 F.2d 936, 942 (4th Cir.1992). In this case, Brinkley has produced a few isolated statements indicating sexist attitudes at HRC, but utterly fails to connect any of the incidents with her eventual demotion and termination.
Certainly, Brinkley’s evidence that Brandel made a statement that he could not work for a woman is an example of a derogatory comment uttered by a coworker. Derogatory remarks may in some instances constitute direct evidence of discrimination, see O’Connor v. Consolidated Coin Caterers Corp., 56 F.3d 542, 548 (4th Cir.1995), rev’d in part on other grounds, 517 U.S. 308, 116 S.Ct. 1307, 134 L.Ed.2d 433 (1996), but “Title VII was not designed to create a federal remedy for all offensive language ... in the workplace.” Hopkins v. Baltimore Gas & Elec., 77 F.3d 745, 754 (4th Cir.1996). Thus, to prove discriminatory animus, the derogatory remark cannot be stray or isolated and “[u]nless the remarks upon which plaintiff relies were related to the employment decision in question, they cannot be evidence of [discrimination].” McCarthy v. Kemper Life Ins. Cos., 924 F.2d 683, 686 (7th Cir.1991). Here, the remark was an isolated event; the record reflects that Brandel uttered it only once. Further, it is plain that there was no nexus between the remark and Brinkley’s eventual termination from HRC. Brandel’s statement was made at a meeting prior to Brinkley’s promotion to GM. It is not a reasonable inference from the evidence that the derogatory comment caused Brinkley’s termination, when in fact the Board ignored the remark and promoted Brinkley shortly after the comment was made. Brinkley was not terminated for over eighteen months after the offensive utterance. Brinkley makes three other factual assertions regarding Brandel that are also insufficient to create a genuine issue of material fact: (1) that male members of the Board highly valued Brandel’s professional services; (2) that reporting relationships were reorganized so Brandel could report to a man; and (3) that several male members of the Board blamed Brinkley for Brandel’s eventual resignation from HRC. The evidence contained in the record, however, belies Brinkley’s claims that the Board’s attitude was related to her sex. Brinkley and Brandel were having a dispute and were not working well together. The record indisputably shows that the Board’s revamping of the reporting relationship between Brinkley and Brandel was a result of the Board’s desire to avoid further conflict. Although Brinkley makes bald assertions to the contrary, there is simply no evidence to support her contentions that the Board acted on the basis of her sex. Finally, Brinkley’s claim that certain male members of the Board valued Brandel’s services highly and held Brinkley accountable for his resignation, simply is not probative of the issue of discriminatory animus.
Additionally, Paschal’s inappropriate statement about the physical attributes of a waitress is not relevant evidence of discriminatory animus leading to Brinkley’s termination, because the decision to demote Brinkley had already been made at the time Paschal began work at HRC. At that time, Brinkley had already been of[609]*609fered, and had rejected, the alternative position of restaurant manager. Although Brinkley was still at the club and still technically the GM while she and the Board were negotiating possible job alternatives or a potential financial settlement, the Board’s decision-making was completed before Paschal arrived. The record does not support the conclusion that Paschal acted in a manner that affected the Board’s eventual decision to terminate Brinkley.
Finally, the treasurer’s statement that a certain male member of the Board was not receptive to women’s views is also inadequate direct evidence to show discriminatory animus against Brinkley. The treasurer’s affidavit merely states her personal opinion in a conclusory fashion. The affidavit cites no specific factual examples supporting her opinion that male members of the Board discredited women’s ideas.
In sum, none of the evidence Brinkley lists, taken singularly or collectively, is sufficient to raise a genuine issue of material fact as direct or indirect proof of discrimination. Although Brinkley points to some unpleasant occurrences during her tenure at HRC, the evidence she has adduced lacks a sufficient connection to the employment decision to be probative on whether her demotion and termination were the result of discrimination.
C.
Next, Brinkley claims that the district court erred when it concluded that she had not proven her prima facie case under McDonnell Douglas. Here, the prima fa-cie case contains four elements: (1) that Brinkley is a member of a protected class; (2) that she suffered an adverse employment action; (3) that at the time of the adverse employment action she was performing at a level that met her employer’s legitimate job expectations; and (4) that the position remained open to or was filled by similarly qualified applicants from outside the protected class. See St. Mary’s Honor Center, 509 U.S. at 506-07, 113 S.Ct. 2742; Karpel, 134 F.3d at 1228; Williams, 871 F.2d at 455. There is no dispute that Brinkley established the first two elements of the prima .facie case. Thus, we focus our review of the district court’s grant of summary judgment to HRC on the third and fourth elements of Brinkley’s prima facie case.
Regarding the third element of the prima facie case, whether Brinkley had been performing her job at a level that met her employer’s expectations, the district court initially noted that there was conflicting evidence presented regarding “how well Brinkley functioned in her role as [GM].” (J.A. at 503.) Ultimately, however, the district court concluded that “Brinkley was not performing her duties in the manner that HRC expected and this caused conflict between employer and employee.” (J.A. at 506.) After a thorough review of the record, we conclude that the district court’s observation and ultimate conclusion that Brinkley was not meeting the Board’s expectations was correct; Brinkley did not adduce sufficient evidence to raise a genuine issue of material fact on this issue.
There is no doubt that the Board was pleased with Brinkley’s performance as business manager prior to her promotion to GM. In deposition testimony, several Board members praised Brinkley’s performance as business manager. A performance evaluation of Brinkley’s work as business manager was conducted in Dé-cember of 1994 and she received an overall rating of “B + .” Brinkley’s good work as business manager is further verified by the Board’s decision to give her the opportunity to become GM of HRC. Brinkley argues that she performed many of the same functions initially assigned to her while she was business manager after she was promoted to GM, and that therefore, because the Board was satisfied with her performance as business manager, she has raised a genuine issue of material fact on the issue of the Board’s satisfaction with her [610]*610overall performance. Brinkley’s argument, however, misses the mark.
After Brinkley was promoted to GM, the Board continued to be satisfied with her performance in the business office, and indeed was satisfied with that portion of her job performance until she was terminated. Unfortunately, work in the business office no longer accounted for Brinkley’s entire job, and the Board was concerned with her performance in other areas. The record conclusively demonstrates that, beginning in December of 1995, the Board determined that Brinkley needed improvement in some important job areas. Specifically, in December of 1995, Brinkley’s evaluation noted that she most needed improvement in five areas. Two of the five areas in which the Board noted a need for improvement involved relationship-building skills. The Board concluded that she needed improvement in developing “[w]orking relationship^] with department managers to form a cohesive management team.” (J.A. at 408.) The evaluation also noted that she needed to concentrate on improving her working relationships with committee members.9
Each of the three extensive deposition excerpts of Board members indicate the same thing: the Board’s concern with Brinkley’s lack of a team-building management style. The Board was not only disturbed by the degeneration of Brinkley’s relationship with Braudel, but also by the fact that Brinkley was unable to mend fences and return to working productively with him after the Board had settled their dispute.
The Board’s continuing concern over Brinkley’s team-building skills reached a peak when Brinkley became angry at the golf pro for circumventing her authority by reporting directly to the Board, and she told him that he could “sink or swim on [his] own.” (J.A. at 37.) The Board concluded that not only had Brinkley given up on managing the golf operation at the club, one of her primary duties, but also that she had done so in a way that irreparably damaged her relationship with the golf pro. Representatives of the Board discussed the fact that they were troubled by Brinkley’s management style at great length in her verbal evaluation conducted July 9, 1996, shortly before Paschal was hired. The crux of the conversation during her verbal evaluation was that the Board was displeased that Brinkley was not able to form a cohesive management team, and that as a result they thought Brinkley should no longer perform the duties of GM.
Thus, the overwhelming evidence supports the district court’s conclusion that Brinkley had not been performing her job satisfactorily. There is a long and well-documented pattern of rising levels of concern among Board members over Brinkley’s apparent inability to bring together the different managers at the club to form a single team. As a result of this undisputed evidence, summary judgment was appropriate because Brinkley could not establish the third element of her prima facie case.
The district court also ruled that Brinkley had not been successful in proving the fourth element of her prima facie case, that Paschal, her replacement, possessed similar qualifications. The district court concluded that “Paschal had superior qualifications for the position of chief of operations of HRC. He had extensive pri- or experience in country club management while [Brinkley] had no such experience prior to her employment with HRC.” (J.A. at 505.)
Here, too, the district court’s conclusion was correct. It is undisputed that Paschal had eleven years of country club management' experience and that he previously [611]*611had been the GM at two other country dubs. The two positions that Brinkley held at HRC were her first exposure to country club employment. Brinkley argues, however, that the district court should have assessed additional factors before concluding that Brinkley and Paschal were not comparably qualified. First, Brinkley notes that she completed her bachelor’s degree in business administration while Paschal had not completed his bachelor’s degree. Further, Brinkley points out that Paschal had been terminated from a hotel manager position listed on his resume, while Brinkley’s employment history was completely favorable.
These additional differences between Brinkley and Paschal, however, do not lead to the conclusion that the two possessed substantially similar qualifications. Instead, Brinkley further demonstrates the contrast between herself and Paschal. Although HRC initially gave its unproven business manager the opportunity to advance within the company and try her hand as GM, when HRC became dissatisfied with Brinkley’s performance it sought a candidate with distinctly different credentials — an extensive history of country club management. Experience in the industry, including two prior GM positions, constitutes a qualitatively different criterion upon which to base an employee’s selection. Cf. Causey v. Balog, 162 F.3d 795, 801 (4th Cir.1998) (noting that experience in the relevant field is a legitimate basis upon which to differentiate employees). Thus, we agree with the district court’s conclusion that Brinkley and Paschal were not similarly qualified for the position and that as a result Brinkley was unable to establish her prima facie case under the McDonnell Douglas proof scheme.
As a result of Brinkley’s inability to establish either the third or the fourth elements of her prima facie case, the district court did not err in granting summary judgment to HRC on Brinkley’s Title VII claim. We note, however, that although helpful, the McDonnell Douglas framework should not be applied in a “rigid, mechanized, or ritualistic” manner. Furnco Constr. Corp. v. Waters, 438 U.S. 567, 577, 98 S.Ct. 2943, 57 L.Ed.2d 957 (1978). Rather, the test is “merely a means to fine-tune the presentation of proof and, more importantly, to sharpen the focus on the ultimate question — whether the plaintiff successfully demonstrated that the defendant intentionally discriminated against her.” Ennis v. National Ass’n of Business & Educational Radio, Inc., 53 F.3d 55, 59 (4th Cir.1995). Although Brinkley may have adduced sufficient evidence from which a reasonable juror could conclude that the Board had treated her callously, such evidence is insufficient to support a Title VII claim. Brinkley has utterly failed to meet her burden of demonstrating that she was demoted and terminated because of sex.
IV.
Brinkley also challenges the district court’s grant of summary judgment on her Equal Pay Act claim. 29 U.S.C.A. § 206(d) (West 1998). She does so on two grounds: (1) that the district court erred when it considered HRC’s affirmative defense that the pay differential between Paschal and Brinkley was based upon a “factor other than sex,” 29 U.S.C.A. § 206(d)(l)(iv), because that affirmative defense was not properly raised in HRC’s answer, but rather was first raised in HRC’s summary judgment motion in violation of Rule 8 of the Federal Rules of Civil Procedure; and (2) that the district court erred in granting summary judgment to HRC on the basis that it had established the “factor-other-than-sex” defense because evidence put forth by HRC was insufficient to establish that affirmative defense at the summary judgment stage of the proceedings. We address these contentions in turn.
Brinkley first asserts that HRC waived its affirmative defense that the pay [612]*612differential between Brinkley and Paschal was the result of “any other factor other than sex,” 29 U.S.C.A. § 206(d)(l)(iv) (West 1998), when it did not raise that defense in its answer, but instead first raised it in its motion for summary judgment. Because the defense was not properly raised, Brinkley argues that it was error for the district court to consider the defense. We conclude that Brinkley was not unfairly surprised or prejudiced by HRC’s late notice that it intended to rely on the “faetor-other-than-sex” defense. Therefore, we determine that the district court did not err when it considered the defense.
Federal Rule of Civil Procedure 8(c) provides, in pertinent part, as follows: “In pleading to a preceding pleading, a party shall set forth affirmatively ... [any] matter constituting an avoidance or affirmative defense.” Fed.R.Civ.P. 8(c). Such defenses should be set forth in “short and plain terms,” Fed R. Civ. P. 8(b), and should be “simple, concise, and direct,” Fed.R.Civ.P. 8(e)(1). The parties agree that the “faetor-other-than-sex” defense to the Equal Pay Act is an affirmative defense. See Brinkley-Obu v. Hughes Training, Inc., 36 F.3d. 336, 344 (4th Cir.1994). Therefore, under Rule 8(c), the defense should have been raised in HRC’s answer. HRC did not note its intention to rely upon the defense in its answer.
Although it is indisputably the general rule that a party’s failure to raise an affirmative defense in the appropriate pleading results in waiver, see 5 Charles Alan Wright & Arthur R. Miller, Federal Practice and Procedure § 1278 (1990), there is ample authority in this Circuit for the proposition that absent unfair surprise or prejudice to the plaintiff, a defendant’s affirmative defense is not waived when it is first raised in a pre-trial dispositive motion, see Peterson v. Airline Pilots Ass’n, 759 F.2d 1161, 1164 (4th Cir.1985) (holding that waiver is not automatic, but requires a showing of prejudice or unfair surprise); see also American Recovery Corp. v. Computerized Thermal Imaging, Inc., 96 F.3d 88, 96 (4th Cir.1996) (evaluating prejudice to plaintiff when considering timeliness of affirmative defense of arbitration); Nasim v. Warden, 42 F.3d 1472, 1475-76 (4th Cir.) (noting that, in limited circumstances, affirmative defense of statute of limitations need not be raised in answer if demonstrated conclusively on the face of the complaint), vacated on other grounds, 64 F.3d 951 (4th Cir.1995) (en banc); Polsby v. Chase, 970 F.2d 1360, 1364 (4th Cir.1992) (noting that affirmative defenses may be pleaded in pre-trial motions and that the district court did not abuse its discretion by permitting defendant to raise an affirmative defense after the answer); vacated and remanded on other grounds, 507 U.S. 1048, 113 S.Ct. 1940, 123 L.Ed.2d 646 (1993). This view is in accord with the vast majority of our sister circuits. See, e.g., Blaney v. United States, 34 F.3d 509, 512 (7th Cir.1994) (stating that an unplead-ed untimeliness defense could be raised in motion to dismiss); Camarillo v. McCarthy, 998 F.2d 638, 639 (9th Cir.1993) (holding that an affirmative defense may be raised at summary judgment absent prejudice to opposing party); Moore, Owen, Thomas & Co. v. Coffey, 992 F.2d 1439, 1445 (6th Cir.1993) (asserting that an affirmative defense may be raised in response to summary judgment motion); Kleinknecht v. Gettysburg College, 989 F.2d 1360, 1374 (3d Cir.1993) (noting that an affirmative defense may be raised at summary judgment absent prejudice); Ball Corp. v. Xidex Corp., 967 F.2d 1440, 1443-44 (10th Cir.1992) (raising affirmative defense in summary judgment motion preserved defense for trial three months later). But see Harris v. Secretary, U.S. Dep’t of Veterans Affairs, 126 F.3d 339, 342 (D.C.Cir.1997) (disagreeing with the majority approach and holding that the approach alters the structure dictated by Rules 8(c) and 15(a) by relieving parties of the need to request amendment and by promoting strategic behavior); Ashe v. Corley, 992 F.2d 540, 545 n. 7 (5th Cir.1993) (disposing of several affirmative defenses not raised [613]*613in the answer without evaluating prejudice to the plaintiff).
In this instance, the district court correctly concluded that Brinkley was not unfairly surprised or prejudiced by HRC’s delay in raising the “faetor-other-than-sex” defense. HRC had raised and litigated this defense during the EEOC’s consideration of the matter. Therefore, Brinkley had fair warning that the defense was likely to arise again in the district court. See American Recovery Corp., 96 F.3d at 96 (finding no prejudice where plaintiff was on notice of defendant’s plan to pursue arbitration prior to answer even though defendant failed to raise it in answer). Further, Brinkley had ample opportunity to respond to HRC’s summary judgment motion in which it initially raised the “factor-other-than-sex” defense. As a result, we conclude that Brinkley was not unfairly surprised or prejudiced by HRC’s delay in raising its affirmative defense; the district court did not err in considering it.
Brinkley next claims that the district court erred when it ruled that HRC had conclusively demonstrated that a “factor other than sex,” 29 U.S.C.A. § 206(d)(l)(iv), motivated its decision to pay Paschal a higher salary than Brinkley had been earning to perform the identical job and granted summary judgment to HRC upon that basis. Brinkley claims that insufficient evidence supported the district court’s ruling in HRC’s favor and that genuine issues of material fact remained to be resolved regarding whether HRC has paid Paschal a higher salary based upon a factor other than sex.

The Equal Pay Act provides:
No employer having employees subject to any provisions of this section shall discriminate, within any establishment in which such employees are employed, between employees on the basis of sex by paying wages to employees in such establishment at a rate less than the rate at which he pays wages to employees of the opposite sex in such establishment for equal work on jobs the performance of which requires equal skill, effort, and responsibility, and which are performed under similar working conditions, except where such payment is made pursuant to (i) a seniority system; (ii) a merit system; (iii) a system which measures earnings by quantity or quality of production; or (iv) a differential based on any other factor other than sex: Provided, That an employer who is paying a wage rate differential in violation of this subsection shall not, in order to comply with the provisions of this subsection, reduce the wage rate of any employee.
29 U.S.C.A. § 206(d)(1).
As under Title VII, a plaintiff bringing a claim under the Equal Pay Act must first establish a prima facie case of wage discrimination. To establish a prima facie case, Brinkley must prove: (1) that her employer has paid different wages to employees of opposite sexes; (2) that said employees hold jobs that require equal skill, effort, and responsibility; and (3) that such jobs are performed under similar working conditions. See Corning Glass Works v. Brennan, 417 U.S. 188, 195, 94 S.Ct. 2223, 41 L.Ed.2d 1 (1974). Plaintiff may use her successor in the position as a salary comparator for purposes of establishing the prima facie case. See 29 C.F.R. § 1620.13(b)(4) (1998).
Unlike a Title VII case, however, under the Equal Pay Act, upon establishing a prima facie case, both the burdens of production and persuasion shift to the defendant. See Brinkley-Obu v. Hughes Training, Inc., 36 F.3d 336, 344 (4th Cir.1994). The defendant bears the burden of proving by a preponderance of the evidence that the wage difference between the male and female employees was the result of one of the four enumerated statutory affirmative defenses: “(i) a se[614]*614niority system; (ii) a merit system; (iii) a system which measures earnings by quantity or quality of production; or (iv) a differential based on any other factor other than sex.” 29 U.S.C.A. § 206(d)(1); see also Strag v. Craven Commun. College, 55 F.3d 943, 948 (4th Cir.1995).
In this case, the district court ruled that HRC had adduced sufficient evidence to establish that Paschal was paid “a differential based on any other factor other than sex,” 29 U.S.C.A. § 206(d)(l)(iv), at the summary judgment stage of the proceedings. The- defendant may prevail on its motion for summary judgment and establish an affirmative defense when it has produced “credible evidence — using any of the materials specified in Rule 56(c) — that would entitle it to a directed verdict if not controverted at trial.” Celotex Corp. v. Catrett, 477 U.S. 317, 331, 106 S.Ct. 2548, 91 L.Ed.2d 265 (1986) (Brennan, J., dissenting); accord Fitzpatrick v. City of Atlanta, 2 F.3d 1112, 1116 (11th Cir.1993); Mesnick v. General Elec. Co., 950 F.2d 816, 825 (1st Cir.1991); International Shortstop, Inc. v. Rally’s, Inc., 939 F.2d 1257, 1264-65 (5th Cir.1991). When the defendant produces such evidence supporting its affirmative defense, the burden of production shifts back to the plaintiff who “must come forward with ‘specific facts showing that there is a genuine issue for trial.’ ” White v. Rockingham Radiologists, Ltd., 820 F.2d 98, 101 (4th Cir.1987) (quoting Fed.R.Civ.P. 56(e)). “[S]ummary judgment will not lie if the dispute about a material fact is ‘genuine,’ that is, if the evidence is such that a reasonable jury could return a verdict for the nonmoving party.” Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 248, 106 S.Ct. 2505, 91 L.Ed.2d 202 (1986). A motion for summary judgment may not be defeated, however, by evidence that is “merely color-able” or “is not significantly probative.”10 Id. at 249-50, 106 S.Ct. 2505.

On appeal, the parties do not dispute that Brinkley established a prima fa-cie case of an Equal Pay Act violation. The first question before us, then, is whether HRC supplied the district court with sufficient credible evidence to support the “factor-other-than-sex” defense. Such evidence is sufficient if the court can conclude that had the same evidence been presented and remained uncontested at trial, HRC would be entitled to a directed verdict. See International Shortstop, 939 F.2d at 1264-65.
HRC presented the following evidence in support of its affirmative defense: (1) Paschal’s resume indicating his extensive country club management experience; (2) Paschal’s deposition in which he stated that he understood that he received a higher salary and better perks because he had a higher salary history, had initially taken the job on a temporary basis, and had a high level of knowledge about the country club industry gained in his prior GM positions; (3) Brinkley’s employment application indicating her lack of country club experience and her low salary history; (4) the fact that when Brinkley accepted the position of GM, she received a $20,000 [615]*615raise from the salary she had been earning as business manager; (5) deposition testimony by members of the Board that they reached mutual agreement on Paschal’s salary based upon what they felt the country club could afford to pay; and (6) deposition testimony by Board members stating that they researched appropriate salary through consultation with the Country Club Managers Association, which indicated that a typical salary for a club of their size was approximately $100,000 per year.
With this evidence, HRC met its burden of producing sufficient evidence, which, if uncontroverted, would have entitled it to a directed verdict had the case proceeded to trial. The evidence presented by HRC points clearly to only one conclusion — that HRC and Paschal followed procedures that are standard in the employment marketplace. HRC reviewed a resume and salary history, assessed its financial situation, compared its situation with that of other similarly situated entities, and negotiated with Paschal to reach a mutually satisfying agreement as to an appropriate salary. The evidence indicates that HRC reached this agreement on the basis of Paschal’s individual merits, not on the basis of his sex. A survey of the record reflects that the Board followed the same procedures when it evaluated Brinkley’s initial salary.11
Our inquiry does not end, here, however. When the defendant produces sufficient evidence in support of its affirmative defense, the burden of production shifts back to the plaintiff. See International Shortstop, 939 F.2d at 1265. The plaintiff must produce specific evidentiary materials that demonstrate the existence of a “genuine issue for trial.” White v. Rockingham Radiologists, Ltd., 820 F.2d at 101 (citing Fed.R.Civ.P. 56(e)). Brinkley has not produced sufficient evidence to meet this burden.12 She has not produced any evidence that indicates that Paschal was paid more, or that she was paid less, because of sex.13
[616]*616In support of her argument that summary judgment was inappropriate, Brinkley points to the gender hostility evident at the club as verified by Brandéis remark that he could not work for a woman as well as Paschal’s inappropriate comment about the physical attributes of a waitress. As we noted earlier, however, Brandéis statement was made before Brinkley was promoted to the position of GM. The Board effectively ignored this isolated comment when it promoted Brinkley, and thus, it is not indicative of a gender-hostile workplace.' Additionally, Paschal was reprimanded by the Board for his statement about the waitress, an action that also indicated that the Board was not harboring gender-based hostility.
Further, Brinkley disputes the contention that Paschal had superior qualifications for the GM position. She notes that Paschal lacked a bachelor’s degree and had been fired from a hotel manager position listed on his resume. These purported deficiencies, however, do not overcome the undisputed fact that Paschal’s resume indicated that he had eleven years of industry experience, and that his experience was significant to the Board members when they made them salary decision.14
Brinkley has produced only the slimmest shreds of evidence from which it might be possible to infer that sex played a factor in the salary differential between her and Paschal. Her version of events, which is not supported by any concrete proof, is simply not enough to controvert the large quantity of undisputed material that HRC put into the record below in support of its [617]*617affirmative defense. Brinkley has not raised a genuine issue of material fact that she was paid less because of her sex. Therefore, we affirm the district court’s grant of summary judgment on Brinkley’s Equal Pay Act claim.
V.
Based upon the foregoing discussion, we conclude that the district court’s grant of summary judgment to HRC on both Brinkley’s Title YII and Equal Pay Act claims were correct. '
