Former champions Roger Federer and Novak Djokovic were in impressive form as they reached the fourth round at Wimbledon in straight sets.
Third seed Federer played superbly in a 7-6 (7-3) 6-4 6-4 win over German 27th seed Mischa Zverev on Centre Court.
Djokovic, seeded second, had earlier looked fired up as he beat Latvia's Ernests Gulbis 6-4 6-1 7-6 (7-2).
Federer will play Bulgaria's Grigor Dimitrov and Djokovic faces Adrian Mannarino in the last 16 on Monday.
Djokovic raises level and focus
An early argument with the umpire seemed to fire up Djokovic, who told the official to "focus" - something he later apologised for - and then appeared to take his own advice.
