Frances Tiafoe’s Wimbledon run is over after losing in the third round to 25th-seeded Karen Khachanov.

Tiafoe produced a major upset by beating third-seeded Stefanos Tsitsipas in straight sets in the first round but didn’t come anywhere close to that performance against Khachanov. The American never earned a break point and lost 6-3, 6-4, 6-4.

Tiafoe had beaten Vasek Pospisil in straight sets in the second round. He also reached the third round at Wimbledon in 2018.
