Federer progresses past Robredo

Roger Federer survived a mid-match wobble today to ultimately breeze into the semi-finals of the French Open at the expense of Tommy Robredo.

The world number one claimed a 7-5 1-6 6-1 6-2 quarter-final victory on Philippe Chatrier court to set up a last-four meeting with either Nikolay Davydenko or Guillermo Canas, but the Swiss did not have it all his own way.

After winning a tight first set, his form dipped dramatically and he landed just 28% of his first serves in the second set.

But Federer regained his composure and went on to play some of his best tennis of the tournament against the ninth seed from Spain.

The third was claimed in just 20 minutes and Federer broke a by-now beleaguered Robredo three times in the fourth to advance to the semis.

The top seed is looking to claim his first Roland Garros title.
