Novak Djokovic reached the Wimbledon quarter-finals with a straight-set victory over France's Adrian Mannarino.
In a match delayed from Monday, the world number four beat Mannarino - who is ranked 51st in the world - 6-2 7-6 (7-5) 6-4 in two hours and 13 minutes.
The Serb appeared unhappy with the condition of Centre Court and also received treatment on his right shoulder during the match.
The 30-year-old will face Czech 11th seed Tomas Berdych in the last eight.
When asked about his shoulder, Djokovic told BBC Sport: "We'll see. It has something which has been dragging back and forth for a while, but I am still managing to play.
