Pegula rallies to reach US Open 2026 fourth round: When data exposes what legends overlook

When Leylah Fernandez raced to a 3-0 lead in the first set, Jessica Pegula did not look like the No. 3 seed she is. Her footwork was slow, her serve lacked depth, and the 22-year-old Fernandez was stepping inside the baseline to dictate play. But I do not write about how players win; I write about what they change in order to win. Legends get praised for their commentary, but I see a wrong number. At the end of the match, Pegula had saved 8 of 9 break points in the final two sets and converted 5 of 7 break opportunities. Fernandez finished with 13 winners but 25 unforced errors. That statistic tells the real story: Pegula stopped letting Fernandez stand close to the baseline, served into the body, and dragged the match into the kind of physical battle where her consistency wins. Pegula now has 11 comeback wins in 2026, tied with Coco Gauff. She can rise to No. 1 if she wins this US Open, but she has never won a Grand Slam. Aryna Sabalenka, meanwhile, extended her US Open winning streak to 16 matches, hitting 10 aces and facing zero break points. Taylor Townsend, who saved 10 of 12 break points in her own match, will be Sabalenka's fourth-round opponent. Pegula's next opponent is Sorana Cirstea. If Pegula starts slowly again, Cirstea has enough experience to punish her. The data says Pegula is elite at adjusting mid-match, but she cannot keep relying on comebacks. She needs to be sharp from the first game. That is the real test of her title credentials.
