PARIS (AP) — The French Open:

Roger Federer might be getting up there in years, but he still keeps winning tennis matches.

Joking that he's "so super old," the 37-year-old Federer returned to the French Open's third round with a predictably straightforward 6-4, 6-3, 6-4 victory over 144th-ranked Oscar Otte.

The 25-year-old Otte lost in qualifying in Paris but got into the main draw when another player withdrew.

Federer saved all four break points he faced and needed just a little more than 1½ hours to advance.

He is playing at Roland Garros for the first time since 2015. Federer completed a career Grand Slam by winning the clay-court major in 2009.

Federer's friend and Swiss countryman, Stan Wawrinka, also moved on in straight sets.

Wawrinka, the 2015 French Open champion and runner-up in 2017, beat Cristian Garin 6-1, 6-4, 6-0.
