U.S. Open runner-up Taylor Fritz moved into the Wimbledon quarterfinals for the third time in four years on Sunday, advancing when his injured opponent, Jordan Thompson , quit while trailing 6-1, 3-0 after 41 minutes.
The unseeded Thompson's movement and power were clearly compromised. The Australian entered the match with back and leg issues and left the court for a medical timeout in the second set Sunday, then stopped after trying to play for three more points.
"It's obviously not the way that I want to go through," the No. 5-seeded Fritz said. "It's just sad. ... Respect to him for coming out. His body's not right."
For Fritz , it was a shorter workday after playing a pair of five-setters and one four-setter earlier in the tournament.
Now the American will meet No. 17 seed Karen Khachanov of Russia on Tuesday for a berth in the semifinals - a round neither has reached at the All England Club.
