Aryna Sabalenka has never been beaten in the first round of the 2025 US Open.
Will her streak be in peril in the face of an unheralded foe on Sunday in Flushing Meadows?
Surprisingly, Sabalenka is still searching for her first Grand Slam title in 2025 after coming up short in the first three major events this year. Sabalenka arrived in New York as the defending US Open champion, but the aura of invincibility that usually follows her in every tournament she competes in has significantly diminished. The quarterfinal loss to Elena Rybakina at the Cincinnati Open, 1-6, 4-6, certainly does not help her cause.
Canada’s Rebeka Masarova will be the first player to take a swing at Sabalenka in this tournament. The 26-year-old Masarova is 12-7 on the hard court this year, but has only won 2 of her last 5 matches. Ranked 109th in the world, Masarova has one top-10 win in her career.

Our Aryna Sabalenka vs Rebeka Masarova Prediction
I am taking Aryna Sabalenka to cover -7.5 Games. She might not be playing her best tennis right now, but the world’s No.1 is still lightyears better than Masarova at this stage.
Sabalenka has a habit of going all-out right off the bat, dominating her first-round opponents to send a strong message to the rest of the field. I expect Sabalenka to do the same on Sunday against a helpless Masarova.
