Pegula and her 'slow-start, strong-finish' habit: What do 11 comeback wins in 2026 reveal about the world No. 3?

Jessica Pegula entered her third-round US Open match against Leylah Fernandez as the No. 3 seed. But in the first set, she won just 1 of 3 service games and failed to create a single break-point opportunity against her Canadian opponent. The set ended 6-3 in Fernandez's favor, and Pegula admitted: "I don't really feel like I was in the first set." The story seemed destined for an upset script. But the turning point came faster than anyone in the Louis Armstrong Stadium stands predicted. Pegula won 5 straight games from the middle of the second set, saved 8 of 9 break points over the final two sets, and closed the match with a 3-6, 6-3, 6-3 victory. She converted 5 of 7 break opportunities in the final two sets while Fernandez finished with 25 unforced errors against just 13 winners. The most striking number of this match was not on the scoreboard. According to tour data, the victory over Fernandez was Pegula's 11th comeback win from a set down in 2026 — tied with Coco Gauff for the most among elite female players. The question is not whether she can win from behind, but why she continuously places herself in that position. Match data reveals two layers of analysis. First: Pegula's ability to turn matches around is world-class. After trailing 0-3 in the second set, she did not lose another service game for the remainder of the match. Her 8-of-9 break-point saving rate (88.9%) ranks in the top 5% on the tour in this category on hard courts in 2026. This demonstrates the 30-year-old's exceptional mental composure at crucial moments. But the second layer is the real issue: why does she always start slowly? Against Fernandez, Pegula's first-set service points won percentage hovered around 50% in her service games. She self-diagnosed her movement as "slow and lazy" — a rare admission from an Olympian-level athlete who typically wins over 75% of points in rallies lasting between 5 and 9 shots. This raises questions about approach. Eleven comebacks are no accident, but they are not necessarily a quality to be celebrated either. On a Grand Slam scale, a habit of losing the first set becomes a structural weakness when facing opponents who can maintain intensity throughout the match. Aryna Sabalenka — the defending champion and No. 1 seed — represents the complete inverse model. In her same-day win over Rakhimova, Sabalenka served 10 aces, committed just 1 double fault, won 74.6% of points in her service games, and did not face a single break point. The difference between a player who enters the court with championship intent and one who needs a full set to find her rhythm is substantial. Examining Sabalenka's match structure reveals why this standard is the true benchmark for a champion. The Belarusian currently holds a 16-match winning streak at the US Open — the longest since Serena Williams' 2026-2026 run of 26 matches. She does not boast particularly superior defensive statistics, but she almost never allows opponents to touch her service games early in matches. Against such a player, any slow-start habit will be punished immediately. Fernandez played her best set of the tournament in this match. She served accurately, returned deeply, and applied relentless pressure on Pegula's early service games. But her collapse in sets two and three — 25 unforced errors, a winner-to-error ratio of just 0.52 — demonstrated her inability to sustain the physical intensity required. This is her limitation. Fernandez reached the 2026 US Open final with similar tactics — aggressive attacking, standing very close to the baseline to take the ball early — but her ability to sustain and control errors has diminished significantly: her fitness cannot support a long match with 30+ continuous movements per set. Pegula, by contrast, possesses the physical foundation to maintain intensity from the second set onward. In recent US Open history, players who repeatedly lose the first set in early rounds and then win the title barely exist as a pattern. The key difference between Gauff and Pegula in this statistic is: Gauff typically loses the first set against opponents playing above themselves, then tightens her game as opponents begin to misfire. Pegula loses the first set because she places herself in a passive state against an opponent's imposed style. These different recovery mechanisms may reflect a deeper issue with systematic pre-match preparation. Pegula also ranks among the most heavily scheduled players in the Top 5, often competing in both singles and doubles at Masters events, which may deplete her opening-set energy. In 2026, fitness has not been a major issue — she has reached at least the quarterfinals in 9 of 11 tournaments entered — but if she must play catch-up from the start of every round at the US Open, the accumulated physical cost of lost sets will create a significant barrier in the semifinal stage. What stands out is how Sabalenka describes her mentality at No. 1. "I think I have a different mindset now," she said in her post-match interview after defeating Rakhimova. It was her first time without losing a break point in a third-round Grand Slam match since Wimbledon 2026. The difference among elite players lies in controlling service games, and Sabalenka has done exactly that over 16 consecutive US Open matches, while observing Pegula's 11 comebacks this year reveals a pattern that leans toward improvisation rather than sustained dominance. Taylor Townsend represents another unpredictable factor in this section. She defeated Shnaider 6-3, 6-4, saving 10 of 12 break points and converting 5 of 7 break opportunities — against Townsend, Sabalenka will face a player who has proven her ability to fight under pressure. Townsend reached the fourth round of the US Open for the third time in her career, while she has only done so once at other Grand Slams. She said: "I've been waiting for the moment to play Sabalenka. That's why I play this tournament — I don't want to be losing to players I need to beat." What happens if Pegula and Sabalenka hold their positions and meet in the semifinals? Sabalenka's tactical intelligence would be tested at a different level, not just through serving. Conversely, Pegula would face an opponent with the best defensive and weakness-exploiting statistics on the tour. She cannot afford to lose another first set to acclimate. Recalling my probability models from tracking these matches: if her first-set loss rate against Top 10 opponents — around 40% — applies, her chances of reaching the final diminish significantly. The greatest problem for a player who wins through resilience is not her ability to save points, but that it masks the root issue and creates a repeating loop: Pegula has allowed herself to fall into difficult positions 11 times this year — and each time she escapes, the habit reinforces itself. When facing someone who never lets go, or whose serve remains impenetrable like Sabalenka's, there may be no opportunity for a "turnaround" to ever materialize. One fact should be acknowledged about Pegula: at 30, she is approaching the end of her career peak — a statistic that led many to underestimate her at the 2026 US Open, where she reached the final. But the data is impersonal and unforgiving: 11 comeback wins in a single year is both the strongest reflection of fighting spirit on tour and the clearest signal of an unsustainable pattern in knockout tournaments. Grand Slam champions over the past decade typically average only 3-4 comeback wins per season — they lose first sets due to something unusual happening, not due to a predictable pattern derived from their playing style. The truth is that in the psychology of a successful player, Pegula belongs to that rare category of players who perform better when backed into a corner — a quality that has built her a solid career over a long period. But at 30, when her career approaches its final chapter, winning a Grand Slam is a goal that cannot be postponed. The real challenge for her is therefore not whether she can stage an 12th comeback, but whether she can break this risky habit before stepping into the final two matches of the tournament. If that does not happen, world No. 3 may represent the summit of her achievements — the finest outcome of a wonderful career. On the other side of the net, Sabalenka does not care about comeback stories. She is simply playing the next match. In modern tennis, champions of her kind — those who deny opponents the opportunity to create turning points — represent the true threat to anyone accustomed to slow starts.
