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.
Rafael Nadal has advice for the kids dreaming about winning the French Open.
"The main thing is, don't think about winning Roland Garros," the 11-time champion said after reaching the third round with a 6-1, 6-2, 6-4 win over German qualifier Yannick Maden.
The stands at Roland Garros are traditionally filled with children on Wednesdays, the traditional midweek day off for schools in France. Nadal was asked during his post-match interview if he could give some tips for success on the Parisian clay to the children who watched him dispatch his opponent.
"Have fun, enjoy, and try your best every single day," Nadal said. "I never thought about (winning Roland Garros). I've just tried my best, enjoyed the process. Think about your personal feeling, the most important thing is to finish your career knowing you gave your best every single day."
