Roger Federer turns focus to Wimbledon after French Open exit
Federer, who won the tournament in 2009, was unable to find a foothold in the match as Wawrinka powered his way to a 6-4 6-3 7-6 (7/4) victory.
It means Federer has failed to reach the last four in three consecutive years at Roland Garros while Wawrinka will now face either Kei Nishikori or Jo-Wilfried Tsonga for a place in the final.
