Pegula and Draper got the better of Emma Raducanu and Carlos Alcaraz 4-2, 4-2 in the first round. In the quarterfinal, they were even more clinical to beat Mirra Andreeva and Daniil Medvedev 4-1, 4-1.
Notably, Swiatek comes to the US Open just hours after clinching the title in Cincinnati after defeating Jasmine Paolini. After their matches on Tuesday, Ruud opened up about the Pole's determination.
"I think it's her will in the end and she decided to show up here, which is wildly impressive because she got to bed 12 hours ago in her hotel in New York and she was here stretching, doing her warmup at 10 a.m.... I looked at Iga like, 'This is determination like I've never seen it before!'" Casper Ruud said (via ATPTour.com).
On Wednesday, August 20, Swiatek and Ruud will face Pegula and Draper in the semis. The winner of their match will face the winner of the other semifinals between Sara Errani-Andrea Vavassori and Danielle Collins-Christian Harrison.
