It's Day 4 of the U.S. Open tennis tournament in Flushing Meadows, New York and continuation of second round action in men's and women's singles included some big upsets.
Carlos Alcaraz's 15-match Grand Slam unbeaten run has ended at the U.S. Open with a 6-1, 7-5, 6-4 loss to Botic van de Zandschulp in the second round. Alcaraz's exit in New York on Thursday night comes after he won the French Open in June and Wimbledon in July. The 21-year-old from Spain won the U.S. Open in 2022 and was 16-2 at the hard-court tournament in his career. This was his earliest loss at any major tournament since bowing out in the second round at Wimbledon in 2021 as a teenager.
Iga Swiatek and Jannik Sinner have flashed their No. 1 form with powerful performances that moved them into the third round of the U.S. Open. Swiatek raced by Japanese qualifier Ena Shibahara 6-0, 6-1, finishing off the match in 65 minutes. It took the 2022 U.S. Open champion longer than that to play the second set of her first-round match, when she needed a tiebreaker that she eventually closed out in 72 minutes. Sinner downed Alex Michelsen 6-4, 6-0, 6-2 in 1 hour, 39 minutes.
Karolina Muchova has eliminated two-time U.S. Open champion Naomi Osaka 6-3, 7-6 (5) in the second round at Flushing Meadows. Osaka was a point from pushing the contest to a third set while serving for the second at 5-4 on Thursday night in Arthur Ashe Stadium. But Osaka missed forehand after forehand until she ceded that game and chucked her racket. Muchova then pulled out the victory in the ensuing tiebreaker. Muchova was the runner-up at the 2023 French Open and made it to the semifinals at the U.S. Open last year before losing to champion Coco Gauff.

Osaka, the two-time U.S. Open champion, is -155 for her second-round match against Karolina Muchova, the 2023 French Open runner-up. Muchova is listed at +120.
In a matchup between Americans, 2020 Australian Open champion Sofia Kenin is an underdog against Jessica Pegula in her first match since eliminating 2021 U.S. Open champion Emma Raducanu. Kenin is at +475, while the No. 6-seeded Pegula is -750.
Carlos Alcaraz and Jannik Sinner are heavy favorites in their second-round matches, while Dan Evans, after his U.S. Open-record match that lasted 5 hours, 35 minutes in the first round, is at -120 in his match against Mariano Navone (-105).
