PARIS (Reuters) - Stan Wawrinka reached the third round at the French Open on Wednesday and said it was his love of tennis that helped him claw his way back from a painful knee injury.
The 2015 Roland Garros champion fell out of the top 200 in the world after undergoing surgery in late 2017, but he has been climbing up the rankings since last year.
