Wimbledon tournament director Jamie Baker said on Friday the grass courts were “good and grippy” despite several high-profile tumbles in the first week of the Grand Slam.

Two-time champion Andy Murray had a nasty fall on Centre Court as he served for a two-sets-to-one lead in his second-round match against Stefanos Tsitsipas late on Thursday but got back up and won the set. US veteran Venus Williams fell heavily in her first-round defeat to Elina Svitolina also on Centre Court on Monday, hurting her already-bandaged right knee. “I was literally killing it, then I got killed by the grass,” said the 43-year-old five-time champion.
