Take our tennis birthday quiz, “Who’s Older?’

Chris Chase

Tuesday is Jo-Wilfried Tsonga's 27th birthday. When we saw his age, we had the same reaction we always when such dates hit the tennis calendar: Initially, we were surprised that he was so old. Then we thought about it and were amazed he was so young.

In honor of Tsonga's birthday, we looked through player profiles to get a refresher course on how old some of the sport's most popular players are. Take our "Who's Older?" quiz to see how you are at evaluating the ages of tennis stars. Was Novak Djokovic born before Andy Murray? Which American teen star has a birthday four days before another?
