Aryna Sabalenka overcame a partisan New York crowd and an in-form Danielle Collins to secure a 3-6, 6-3, 6-2 win on Monday and set up a U.S. Open quarterfinal against familiar foe Karolina Pliskova.
American Collins came out firing to take the first set, but the tide turned in the second when sixth seed Sabalenka won a marathon service game to lead 4-3.
Sabalenka rolled on from there, breaking Collins in the next game and capturing the set with her fifth ace.
