Second seed Novak Djokovic looked fired up and on form as he beat Latvia's Ernests Gulbis in straight sets to reach the fourth round at Wimbledon.
The three-time champion from Serbia won 6-4 6-1 7-6 (7-2), reeling off nine games in a row at one stage.
He goes on to face Adrian Mannarino, who beat fellow Frenchman and 15th seed Gael Monfils 7-6 (7-3) 4-6 5-7 6-3 6-2.
Seven-time champion Roger Federer plays German 27th seed Mischa Zverev in Saturday's final match on Centre Court.
An early argument with the umpire seemed to fire up Djokovic, who told the official to "focus" and then appeared to take his own advice.
