Novak Djokovic's white tennis shoes with the green “23” printed on the heel might have to be replaced soon.
The seven-time Wimbledon champion has won 23 Grand Slam singles titles, and he could add to that total on Sunday, July 16, if he wins three more matches at the All England Club.
“Well, obviously if it happens in less than a week's time that I reach the 24, then we'll have to use the 24, I guess,” Djokovic said. “It's not going to be a big problem to do that.” Djokovic reached the Wimbledon quarterfinals for the 14th time on Monday, July 10, beating Hubert Hurkacz 7-6 (6), 7-6 (6), 5-7, 6-4 in a match that started Sunday, July 9, on Centre Court. He will next face Andrey Rublev for a spot in the semifinals.
