US Open 2025: Djokovic, Sabalenka & Shelton's Can't-Miss Day 1 Matches!

The U.S. Open 2025 is kicking off with a bang! Forget easing into the tournament; the first day is packed with must-see matches featuring some of the biggest names in tennis. This year introduces a new format with three days dedicated to first-round action, making the opening matches even more spread out and accessible to fans.

Top Matches to Watch on Day One

Ben Shelton vs. Ignacio Buse

Ben Shelton, fresh off his ATP Masters 1000 title in Toronto, opens his U.S. Open campaign against Ignacio Buse. This could be Shelton's first and last daytime match in Arthur Ashe Stadium. Buse, a Peruvian qualifier, will be looking to cause an upset. While Buse is coming off a strong performance in Cancun, Shelton presents a formidable challenge.

Aryna Sabalenka vs. Rebeka Masarova

World No. 1 and defending champion Aryna Sabalenka faces Rebeka Masarova. Sabalenka has been dominant this year, but Iga Świątek is hot on her heels. Sabalenka's serve has shown vulnerability, but she's still the favorite to advance. Masarova pushed her to a tiebreak at the Berlin Open, so this match could be closer than expected.

Novak Djokovic vs. Learner Tien

Novak Djokovic, a 24-time Grand Slam champion, takes on Learner Tien in a classic first-round encounter. Expect Djokovic to showcase his experience and skill against his younger opponent.
