The invincible Iga Swiatek is coming off her third title in the past four years on the French Open’s red clay. Last September, she won a championship on the U.S. Open’s hard courts for the first time. That’s also the surface used at the Australian Open, where she’s been to the semifinals.

And what about on grass courts? Wimbledon, which begins Monday, has been her least successful Grand Slam tournament so far. Swiatek is just 5-3 at the All England Club — compare that to her 28-2 mark at Roland Garros, for example — and those three losses came in the first round, third round and fourth round.
