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

In the tense atmosphere of the 2026 US Open round of 32, Jessica Pegula created a moment that left the entire crowd stunned. Despite starting the match with a slow pace, the No. 3 seed rallied to defeat Leylah Fernandez 6-3 6-7 6-3, advancing to the fourth round. The first observation: Pegula held only 1 out of 3 service games in the first set, forcing no break points on Fernandez's serve. That was the first image of a surprising night. The 2026 US Open is taking place on hard courts in the US, where the atmosphere from the Arthur Ashe Stadium crowds adds huge pressure. The football following spirit – according to the exact spirit of following major matches – is now not football but tennis, where long-term data decides everything. Pegula, with stable form but prone to weaknesses in the opening set, faced Fernandez – the Canadian girl trying to maintain pace with aggressive play. Data shows Pegula held only 33.3% of service games in set 1, in the bottom 25% vs tour. But this weakness was later compensated by excellent tactical adjustment ability. In sets 2 and 3, Pegula saved 8 out of 9 break points, proving high fighting spirit. Core insight: The relationship between slow start and comeback shows Pegula is not a player running with early pace, but one who waits and exploits opponent mistakes when the match enters the second half. 2026 historical data shows Pegula has 11 comeback wins, equal to Gauff, and this is not accidental. Fernandez, with a winner-to-unforced-error ratio of only 0.52, left 25 unforced errors, indicating unsustainable attacking performance. Many fans might think this was an easy win for Pegula, but the reality is it is the result of tactical adaptation. Many commentators outside may doubt Pegula because of slow start, believing she is easy to eliminate before Sabalenka – who is on a 16-match US Open winning streak. However, long-term data shows Pegula has the ability to adjust serve placement and first-ball aggression after the opening set, helping her create a break in set 2 with 5 out of 7 break point conversion. This reflects that Pegula's slow start is not a fixed factor, but part of a long-term strategy to conserve energy. However, if the opponent applies strong pressure from the start, like Sabalenka with 74.6% service points won, Pegula could clearly expose her blind spots. Townsend, with 83.3% break point saved, created drama in the previous match, but Sabalenka still prevailed. Pegula's path: After Fernandez, she may face Cirstea or Navarro, where data shows Pegula needs to improve return positioning to avoid early breaks. Takeaway: Based on my experience following matches over many seasons, I see positive internal signals for Pegula if she maintains focus after the opening set. The question is whether Sabalenka can maintain the streak or not, and whether Pegula can turn vulnerability into advantage by adjusting warm-up routines. It cannot be firmly asserted after one match, but data shows Pegula is in peak form with high resilience. Numbers do not lie. It is just that we must ask the right questions. There are things that only appear when we sit quietly longer than a game. A new team, like a new watch, needs time to run on time. I don't remember what I wrote. I remember what I counted. The rhythm keeper does not make the music himself, but without him everything will be out of tune. Transfer rumors are a math problem: lack of data, excess unknowns, all assumptions. Fans have the right to live in emotion; my task is to live in data. In 2026, I wrote to relieve. Now, I write to answer the question of 2026.
