The US Open 2025 is underway, and several players are generating significant buzz as potential contenders for the title. From seasoned champions to rising stars, here are five players to keep a close watch on as the tournament progresses:

Novak Djokovic: Even at 38, Novak Djokovic remains a force to be reckoned with. The 24-time Grand Slam champion's experience and mental fortitude make him a formidable opponent. Despite recent physical struggles, as seen in his first-round match against Learner Tien, Djokovic's tenacity and ability to perform in crucial moments cannot be underestimated. Djokovic acknowledged that he needs to feel physical improvement in his second-round encounter. He has not won a Grand Slam title since the 2023 US Open.

Jannik Sinner: As the top seed and defending US Open champion, Jannik Sinner entered the tournament as a favorite after dominating the hard-court season. Sinner has been dominant on hard courts, winning the past three hard-court majors. Although he had to retire from the Cincinnati final due to illness, Sinner stated that he has "recovered mostly" and is aiming to be at 100% soon. Sinner could become the seventh man in the Open Era to win three Grand Slam titles in the same year.

Carlos Alcaraz: The 2022 US Open champion, Carlos Alcaraz, is a significant threat to Sinner's title defense. Alcaraz has been in excellent form, winning the Cincinnati Open and demonstrating his ability to thrive on the big stage. Alcaraz is aiming to continue his impressive season at the US Open, which could have huge implications on the PIF ATP Rankings. Alcaraz said that he has to be focused on the return and trying to put as many returns as he can.

Iga Swiatek: On the women's side, Iga Swiatek is considered a top contender. Coming off a dominant Wimbledon victory and a recent win in Cincinnati, Swiatek is surging once more. Swiatek has been described as humble. Swiatek has gone 49-12 this year with two titles to her name.

Madison Keys: Following her Australian Open victory in January, Madison Keys entered the US Open with a sense of freedom. However, Keys, seeded sixth, suffered a surprising first-round defeat to Renata Zarazua. Despite the early exit, Keys' potential for strong performances on her home court keeps her on the radar. Keys reached the US Open final in 2017.
