Federer through in straight sets again

Roger Federer came through a mid-match wobble to wrap up a straight-sets win over Stanislas Wawrinka and move into the French Open quarter-finals today.

Defending champion Federer made his most convincing start of the tournament so far but also went close to dropping a set for the first time before sealing a 6-3 7-6 (7/5) 6-2 victory in one hour and 56 minutes on a windy Philippe Chatrier Court.
