PARIS — Roger Federer has not dropped a set at the French Open and eased into the quarterfinals with a 6-2, 6-3, 6-3 win against the unseeded Argentine Leonardo Mayer on Sunday.
With temperatures reaching 88 Fahrenheit (31 Celsius) on a sun-soaked center court, the third-seeded Federer was rarely troubled in beating Mayer for the fourth time in four meetings.
Federer has not played at Roland Garros since 2015, deciding to skip the clay season for health reasons until returning to the surface this year.
In his last French Open, four years ago, Federer lost in the quarterfinals to his Swiss countryman Stan Wawrinka in straight sets.
