Paris: Roger Federer waltzed into quarter-finals of French Open by giving Argentine Leonardo Mayer a 6-2 6-3 6-3 masterclass on Sunday.
Federer won his only French Open in 2009 and remains on course for a semifinal showdown with Rafael Nadal, the defending champion at Roland Garros. Nadal was facing another unseeded Argentine, Juan Ignacio Londero, later on Sunday.
After dropping his serve to lose the second set, Mayer angrily swiped the ball away and was given a code violation warning for ball abuse.
Federer was looking so clinical and assured that the crowd at Philippe Chatrier groaned in disbelief when he missed an easy-looking forehand volley at the net, early in the third set.
It was the second time Federer has beaten Mayer at a Grand Slam — the other also coming in straight sets, in the first round of the U.S. Open in 2015.
That was also the last year Federer played at Roland Garros, before skipping clay entirely until returning to the surface this year.
