After a small hiccup, Roger Federer quickly found his stride again to advance at Wimbledon.
Federer dropped a set for the first time this week but never looked in real trouble against Sam Groth, beating the hard-serving Australian 6-4, 6-4, 6-7 (5), 6-2 in the third round on Saturday.
Federer never faced a break point on Centre Court and only failed to break Groth's serve in the third set, where he double-faulted to give the Australian a 4-3 lead in the tiebreaker.
Federer is bidding for a record eighth Wimbledon title. He has not lost to an Australian at a major since his first Grand Slam tournament, when he was beaten by Pat Rafter at the 1999 French Open.
