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.

Djokovic, who is looking for a record-equaling eighth Wimbledon title and a record-breaking 25th Grand Slam title, battled and then surged past the Italian No. 22 seed Cobolli 6-7 (6), 6-2, 7-5, 6-4 to set up Friday’s date with Sinner.
