Alcaraz holds off Humbert in 4 sets to reach Wimbledon quarterfinals

Defending Wimbledon champion Carlos Alcaraz came up with the big shots when it mattered most to hold off Ugo Humbert and reach the quarterfinals with a 6-3, 6-4, 1-6, 7-5 win on Centre Court on Sunday in London.

"I felt great playing today, I think I played at a really high level," said Alcaraz, who will next play the winner between No. 12 Tommy Paul and Roberto Bautista Augut.

She had her left thigh taped as she served for the match for a second time but was broken again — double-faulting on break point — and was in tears by the end of that game, with her movement clearly restricted.

Keys tried to play on but the American finally went to the
