Carlos Alcaraz said ahead of his Wimbledon quarter-final against Cameron Norrie that playing the left-handed British player can be a nightmare and for a few minutes it looked as though the defending champion might be in for a fright on Tuesday.

LONDON -- LONDON (AP) — Novak Djokovic began expressing a heartfelt thought about returning to the semifinals at the All England Club — “It means the world to me,” he was saying, “that I’m still able, at 38, to play (in the) final stages of Wimbledon” — when the Centre Court crowd interrupted with yelling and applause.

Djokovic is looking for a record-tying eighth Wimbledon title, but Sinner has beaten him in their last four meetings, including in French Open semifinal.
