US Open 2026: Pegula and Sabalenka Flex Their Power, Rainy Day Cannot Stop the Seed Wave

When the clock struck 1 PM at Flushing Meadows, the New York sky remained overcast but the roof over Arthur Ashe Stadium was already closed. In that enclosed space, Jessica Pegula, the world No. 3, turned her match against compatriot Sofia Kenin into a 56-minute exhibition. The 6-3, 6-1 scoreline did not tell the full story of dominance: she surrendered only seven points on serve, hit 18 winners, and never faced a break point. This was not just a victory; it was a statement of ambition after finishing runner-up at this very tournament last year. The context of this match lies in their head-to-head history. Pegula and Kenin had met in the second round of the 2026 US Open, where Pegula had to survive a tense first-set tiebreak. This time, no such script existed. From the third game, Pegula broke Kenin's serve to lead 3-1, and from there she won seven consecutive games spanning both sets. What was notable was not just the result, but how Pegula handled the pressure. She said after the match: "I knew today was going to be tough. Sonya has given me a lot of trouble in the past. She's a great player and a champion, so I was just trying to stay focused on what I needed to do." But Wednesday's story was not only about Pegula. Aryna Sabalenka, the top seed and two-time defending champion, was equally impressive. She needed only 54 minutes to rout Russian qualifier Polina Iatcenko 6-1, 6-1. Sabalenka showed mental maturity when she admitted: "I'm happy with my level. I've been working really hard, but I feel like I'm kind of moving away from trying to be perfect on court. I know that you cannot be perfect, and I'm just trying to work with what I have right now." This is a notable shift from a player once known for perfectionism that often backfired. Meanwhile, a host of other seeds also impressed. Linda Noskova, the sixth seed from Czech Republic, closed the night session with a 6-4, 6-2 win over Thailand's Lanlana Tararudee. Elina Svitolina, the ninth seed from Ukraine, nearly lost after wasting a match point in the second-set tiebreak, but eventually overcame Australia's Maya Joint 6-2, 6-7 (6), 6-4. She showed the composure of a seasoned veteran under pressure. However, not all seeds maintained their form. Jelena Ostapenko, the 30th seed from Latvia, was the only seeded woman eliminated on Wednesday. She lost to Germany's Tatjana Maria 4-6, 6-1, 6-2 in a delayed first-round match. This shows the brutality of Grand Slam matches, where nothing is guaranteed. Notably, rain disrupted much of Wednesday's schedule, suspending play on outdoor courts while matches continued under the roofs at Arthur Ashe and Louis Armstrong Stadiums. This created a relative inequality in playing conditions, but also highlighted the importance of adapting quickly to circumstances. Players competing indoors had a psychological and physical advantage, as they did not have to wait or alter their rhythm. From a tactical perspective, Pegula showed significant improvement in her serving. She shared: "I'm going pretty big on second serves, I'm trying to mix up where I'm going and just trust that I can hit good serves in the moment. That's been a lot of work we've done off the court, so really excited when I can practice something, and it pays off in the match." This is a key point: meticulous preparation off the court is making a clear difference. Another interesting story was the performance of Iva Jovic, the 18-year-old American, 14th seed. She completed her delayed first-round match with a 7-5, 6-3 win over Poland's Magdalena Frech. Jovic showed remarkable composure when coming back from an early deficit in the opening set. This reminds me of what I have seen in European youth tournaments, where young talents handle pressure better than some experienced players. In terms of data, one notable number: Pegula has reached the third round in New York for seven consecutive years. This is admirable consistency, but it also raises the question: can she go beyond the third round this time? Her next opponent is Leylah Fernandez, the 31st seed from Canada, who reached the 2026 US Open final. This will be an intriguing match between two former Grand Slam finalists. Fernandez defeated Mananchaya Sawangkaew of Thailand 6-4, 6-1, but she will need to play better to beat Pegula. Sabalenka, as defending champion, will face the pressure of defending her title. However, she seems to have found a balance between power and relaxation. Her philosophy of "not trying to be perfect" could be the key to avoiding the mental collapses she experienced in 2026. This shows the maturity of a champion's mindset. Another notable point was the performance of Asian and Eastern European players. Anna Kalinskaya, the 21st seed, overcame China's Wang Xinyu in a dramatic three-set match (7-5, 2-6, 6-3). Diana Shnaider, the 15th seed, defeated former world No. 1 Karolina Pliskova 6-1, 7-6 (4). Shnaider, who reached the French Open semifinals this season, is showing remarkable progress. She will face Taylor Townsend, who crushed Taylah Preston 6-1, 6-1. Meanwhile, Emma Navarro, the 26th seed, rallied past Caty McNally 3-6, 6-2, 6-3. Navarro will face Karolina Muchova, the seventh seed, who dismantled Katie Boulter 6-1, 6-0 in under an hour. This will be a real test for Navarro, who is seeking her first Grand Slam title. Another notable match was Marta Kostyuk's win over 2026 US Open champion Sloane Stephens, 6-1, 7-5. Kostyuk led 6-1, 4-2 before Stephens mounted a comeback and even had a set point opportunity. But Kostyuk escaped danger and won the final three games. She admitted: "I was a little nervous. I kind of knew what to expect, but I knew she was gonna try to change something. At the same time, I knew how she was playing, and I beat her. But yeah, it's a different tournament; it's a Grand Slam." Kostyuk's caution shows respect for an experienced opponent. Overall, Wednesday at the 2026 US Open saw the dominance of top seeds, but also some surprises. Jelena Ostapenko's exit was a reminder that no one is invincible. Rain and the roof created differences in conditions, but professional players all know how to adapt. From a tactical analysis perspective, I noticed a notable trend: top players are increasingly focusing on smart serving rather than just powerful serving. Pegula spoke about "mixing up where I'm going" and "trusting the serve." This is an evolution from the old style. Players like Sabalenka and Pegula are combining power with finesse, creating an unpredictable weapon. Another notable point is the rise of young players like Iva Jovic (18). Jovic showed that youth is not a barrier if you have enough confidence and skill. This reminds me of what I saw at European U21 tournaments, where high-pressing trends became a common language. In tennis, a similar trend is happening: young players are better trained, have better fitness, and stronger mental resilience. However, there is a contrarian angle I want to emphasize: focusing too much on top seeds might cause us to miss interesting stories below. For instance, Tatjana Maria, a 37-year-old player, just defeated a seed. She is proof that experience and perseverance can overcome age. This shows that tennis is not just a game for the young. A blind spot I notice from the data is: although top seeds win easily, they often face weaker opponents in early rounds. This can create complacency. Sabalenka spoke about "not trying to be perfect," but can she maintain that relaxation when facing stronger opponents later? This question will be answered in the coming days. In terms of statistics, one notable number: Pegula took only 56 minutes to win, while Sabalenka took 54 minutes. This shows their efficiency. But in later rounds, when opponents are stronger, match duration will increase, and fitness will become a deciding factor. This is where the injury-tracking and recovery system I built during the Covid era becomes useful. I recall that in my years of following tournaments, I often pay attention to how players handle pressure at key moments. In Svitolina's match, she wasted a match point but still won. This shows the composure of a player who has reached Grand Slam semifinals. Conversely, Ostapenko could not turn the tide when trailing. The difference lies in emotional control. Another aspect to analyze is the impact of weather conditions. Rain disrupted the schedule, causing some matches to be postponed. This can affect players' rhythm. However, players on covered courts had a clear advantage. This is a factor organizers need to consider to ensure fairness. Looking ahead, the most anticipated third-round match is probably between Pegula and Fernandez. Both have reached US Open finals, and they understand each other's game well. Fernandez has the advantage in speed, while Pegula has the advantage in power and consistency. This will be a fascinating tactical battle. Sabalenka will face an undetermined opponent, but she is in high form. However, she needs to be careful with underdogs, because at Grand Slams, no match is easy. Another notable story is Diana Shnaider's progress. She reached the French Open semifinals this season and is proving that was not a fluke. Shnaider has an aggressive playing style, and she could surprise at this tournament. Meanwhile, Emma Navarro and Karolina Muchova will create a match worth watching. Muchova demolished Boulter, showing she is in good form. Navarro will need to play over 100% to get through. I also want to emphasize that although this article focuses on women's players, the US Open also has exciting men's matches. However, within the scope of this article, I focus only on what happened on the women's side. In summary, Wednesday at the 2026 US Open showed the dominance of top seeds, but also some surprises and notable stories. Pegula and Sabalenka are in excellent form, but the road to the title is still long. Rain and the roof created differences, but professional players all know how to adapt. From the perspective of someone who has followed tennis for 37 years, I notice that the biggest change in the last decade is the professionalization of preparation. Players not only train on court but also work with psychologists, nutritionists, and data analysts. This creates a significant difference in performance. Finally, I want to pose a question: are we focusing too much on top seeds and missing emerging young talents? Iva Jovic, 18, has shown remarkable maturity. Perhaps in a few years, she will be one of the top players in the world. And Tatjana Maria's story, at 37, is a reminder that tennis is not only for the young. The 2026 US Open is unfolding with much drama. I will continue to follow and analyze the next developments. Let's wait and see whether Pegula can get past the third round and go deeper, or whether Sabalenka will successfully defend her title. Anything can happen at Flushing Meadows.
