Second-seeded Ashleigh Barty, the 2019 French Open champion who was in the midst of a breakout year, crashed out of the United States Open in the fourth round on Sunday.
Barty looked sluggish and sloppy as No. 18 Wang Qiang of China beat her, 6-2, 6-4, and reached the quarterfinal of a Grand Slam event for the first time in 21 appearances.
Wang will play the winner of the match between No. 8 Serena Williams and No. 22 Petra Martic, scheduled for later Sunday. If it turns out to be Williams, it will be the first time she has met Wang on court; Williams pulled out of their scheduled match at the Miami Open in March because of a knee injury.
