Six-time champion Roger Federer came within two points of crashing to his worst Wimbledon defeat in 10 years on Friday before battling from two sets down to beat French 29th seed Julien Benneteau.
Federer clinched an eighth career fightback from two sets to love down to win 4-6 6-7 (3-7) 6-2 7-6 (8-6) 6-1 and will face unseeded Belgian Xavier Malisse for a place in the quarter-finals.
