Jessica Pegula rallies from slow start to reach US Open fourth round

Jessica Pegula, the No. 3 seed at the 2026 US Open, demonstrated extraordinary strength by coming back from a deficit against Leylah Fernandez in the round of 16. Data shows she held only 1 of 3 service games in the first set, but completely transformed afterward. Meanwhile, Aryna Sabalenka continues her 16-match winning streak at the US Open, with 74.6% service points won. This article analyzes these metrics in detail based on match data. The 2026 US Open is taking place on hard courts, the final Grand Slam of the year. Pegula is in peak form, with 11 comebacks in 2026. Fernandez is an aggressive player but has 25 unforced errors. In other matches, Emma Navarro, Sorana Cirstea, Marta Kostyuk, Linda Noskova, and Anna Kalinskaya also contributed to the round of 16. Technical analysis shows Pegula's serve placement improved significantly after the first set. Fernandez's return positioning neutralized Pegula's serve in set 1, but did not maintain in subsequent sets. Sabalenka continues dominance with 10 aces and 1 double fault, winning 74.6% service points. Townsend also stands out with 10 of 12 break points saved. Data never rushes. Those who rush are wrong. Pegula saved 8 of 9 break points in sets 2 and 3, showing excellent tactical adjustment. Fernandez's winner to unforced error ratio is only 0.52, indicating inefficiency in attack. Sabalenka's 16-match US Open streak is historic, compared to Serena Williams 2026-2026. Although Pegula reached the fourth round, the slow start weakness could be exploited by stronger opponents. Townsend has upset potential against Sabalenka with aggressive return game. Pegula's 11 comeback wins tied with Gauff is elite resilience, but may not be enough if the opponent maintains intensity throughout the match. The next round signal shows Sabalenka remains the top contender. Pegula needs to improve first set performance to avoid risk. The 2026 US Open continues to bring interesting surprises with data and tactics.
