LONDON (AP) — Novak Djokovic played the first match of this year's Wimbledon tournament under a closed roof on Centre Court, and he won it in straight sets.

The three-time champion at the All England Club beat Adrian Mannarino 6-2, 7-6 (5), 6-4 in a fourth-round match that was postponed from Monday.

During the third set, with Djokovic already up a break, the second-seeded Serb asked for a medical timeout and a trainer examined and stretched his right shoulder. Djokovic appeared to grimace in pain a couple of times as his shoulder was being checked.

Djokovic will face Tomas Berdych, a man he has beaten 25 times in 27 matches, in the quarterfinals on Wednesday.

Meanwhile, Garbine Muguruza is in the Wimbledon semifinals. The runner-up at the All England Club in 2015 beat Svetlana Kuznetsova 6-3, 6-4 on No. 1 Court in a match that was delayed at the start by rain. Unlike Centre Court, the No. 1 Court does not have a roof.

Muguruza won the French Open last year, but followed up her first major title by losing in the second round at Wimbledon.
