Polina Iatcenko is about to get the biggest match of her career. Tonight at the U.S. Open, she will face Aryna Sabalenka in the second round after both won their opening matches, with Sabalenka chasing a third straight title and Iatcenko trying to keep the best Grand Slam run of her career alive.
Sabalenka advanced with a straight-sets win over Camila Osorio, while Iatcenko upset Renata Zarazua on Sunday to reach a stage she had never reached before at a Grand Slam. They have never played each other in a professional match, which gives this meeting a fresh edge even before the first ball is struck.
The weight of the matchup sits with Sabalenka. She won the U.S. Open in 2024 and 2025, and only Chris Evert and Serena Williams have won it three straight years. A win tonight would put her one step closer to joining that company, which is why the second round already feels bigger than the round label suggests.
Iatcenko’s case is different but no less real. She won the Caldas da Rainha Open in Portugal last year, but last month she fell in the first round of qualifying at the Cincinnati Open, and before this week her last non-qualifying WTA match win came in January at the Workday Canberra International. Her upset of Zarazua was not just an opening-round result; it was a marker that she can now carry form onto the sport’s biggest stage.
That is what makes this pairing tricky for Sabalenka despite the history on her side. She arrives after losses to Ekaterina Alexandrova at the National Bank Open and Sara Bejlek at the Cincinnati Open, reminders that even a player with an 85% career win rate at the U.S. Open is not moving through the field without pressure. Her first-round win was clean, but the recent defeats left enough doubt to make a first meeting with a rising opponent more interesting than the ranking sheet would suggest.
The next answer comes quickly. If Sabalenka handles the moment, she stays on the track toward a rare third straight U.S. Open title. If Iatcenko can turn her first Grand Slam breakthrough into another upset, the name Polina Iatcenko will move from one good week to a run that started to look like something bigger.
