Novak Djokovic is more than a decade older than any other man in the Wimbledon semifinals. He says it motivates him to see if he can keep going toe-to-toe against the younger players at the top of tennis these days.

Jannik Sinner and Ben Shelton will play at the Wimbledon quarterfinals on Wednesday, July 9, at 9:10 a.m. ET/6:10 a.m. PT at the All England Lawn Tennis and Croquet Club in London. This match isn't the first time Sinner and Shelton have played each other.

Ben Shelton had high praise for Jannik Sinner after losing to the Italian in the Wimbledon quarterfinals on Wednesday.
