Roger Federer overcame the big-serving Sam Groth in four sets to reach the fourth round at Wimbledon on Saturday.
The Swiss second seed, 33, won 6-4, 6-4, 6-7 (5-7) and 6-2 and faces Spanish 20th seed Roberto Bautista Agut next.
Despite firing the second-fastest serve in Wimbledon history with a 147mph effort, Australian Groth, 27, was outclassed by the seven-time champion.
Federer lost his first set of the tournament against Groth but recovered to break the world number 66 twice in the fourth set.
The Swiss said of Groth: “He’s got a big serve and is a good mover coming forward, but I need to focus on my serving games and I dealt with that very well.
“I’m very happy with the way I played and I’m very pleased with the first week.”
Elsewhere Croatia’s Marin Cilic beat American John Isner, winning 12-10 in the final set.
The match was suspended at 10-10 in the fifth set on Friday because of bad light but resumed on Saturday, with Cilic winning two games for a place in the last 16.
Dustin Brown, who defeated Rafael Nadal in round two, lost 6-4, 7-6 (7-3), 4-6 and 6-3 against Serbia’s 22nd seed Viktor Troicki.
