PARIS — Some quick thoughts on Day 10 of the French Open...
• Before this year, Roger Federer’s last French Open match was a defeat to his friend, Swiss countryman and metaphorical little brother Stan Wawrinka. That was 2015. That was a quarterfinal. That was a match played on Court Suzanne-Lenglen. Since then, Federer has picked up three more majors, and Wawrinka would go to win the French title that year, as well as the U.S. Open the following year. Here they were today, ages 37 and 34, playing each for the 26th time. Again, a French Open quarterfinal.
