World number one Novak Djokovic reached his 13th consecutive Grand Slam semi-final on Wednesday with a 7-6 (7/5), 6-4, 6-3 win over Czech seventh seed Tomas Berdych in the Wimbledon quarter-finals.
Djokovic has been feeling pretty good about his game, as well. He had 36 winners and 13 unforced errors against Berdych.
“I’ve been playing my best tennis of the year on grass,” Djokovic said. “I’m glad because it’s not my most preferred surface. Hopefully, my experience can help me.”
The top-seeded Serb overcame a double break early in the second set to advance to Friday’s semifinals, where he will play Juan Martin del Potro.
Djokovic won the Wimbledon title in 2011, but lost to eventual champion Roger Federer in last year’s semifinals.
