Andy Murray aims to join Novak Djokovic and Roger Federer in the third round as Wimbledon scrambles to clear a backlog of matches caused by rain delays.

Play on the outside courts started 30 minutes earlier than usual on Thursday under cloudy skies, with some rain forecast for later in the day.

Murray, the 2013 champion who is seeded No. 2, was set to play the second match on Centre Court against 76th-ranked Yen-hsun Lu of Taiwan.

Other men in action include No. 5 Kei Nishikori, No. 6 Milos Raonic and No. 7 Richard Gasquet.

Among the women, French Open champion and No. 2 Garbine Muguruza was set to play on Court 1 against Jama Cepelova.

More than a dozen players are still stuck in the opening round because of rain delays.
