The U.S. Open at Flushing Meadows is poised to be one of the most wide-open tournaments in recent memory, with several top contenders facing unique circumstances as they vie for the title. Alexander Zverev, Jannik Sinner's withdrawal due to a knee injury has elevated Zverev to the top seed. Ranked second in the world, Zverev is in strong form, holding an 18-2 record in majors this year. After securing his first Grand Slam title at the French Open and reaching the Wimbledon final, he is considered a strong favorite to claim the championship in New York.

Carlos Alcaraz, the defending champion, returns to Flushing Meadows as a significant question mark. Despite his impressive 24-3 all-time record at the U.S. Open, Alcaraz has not competed since April due to a four-month layoff caused by a wrist injury. The No. 2 seed faces a challenging opening draw, potentially meeting Roman Safiullin, who defeated him in Paris in 2023, and possibly Ben Shelton in the quarterfinals.

Novak Djokovic, at 39, continues to demonstrate remarkable longevity. Seeded fourth, Djokovic has reached the Australian Open final and the Wimbledon semifinals this year. A highly anticipated semifinal clash with Alcaraz could be on the horizon, showcasing a matchup between two of the sport's leading figures.

Ben Shelton is another player generating buzz. Ranked ninth and seeded eighth, Shelton has been in exceptional form, recently becoming the first man since Rafael Nadal in 2019 to defend his Montreal title. The 23-year-old lefty also reached the fourth round in Hamburg and could face Alcaraz in the quarterfinals, posing a potential upset threat.

Taylor Fritz rounds out the group of notable contenders. Ranked 12th and seeded ninth, Fritz recently captured his first title of the year in Washington and reached the quarterfinals at both Wimbledon and Cincinnati. Having made the U.S. Open final in 2024 and the quarterfinals last year, Fritz is considered a genuine threat for another deep run in the tournament.
