After winning both matches Thursday (including a third-set tiebreak, comeback win against Borna Coric in the nightcap), Roger Federer pulled out of his quarterfinal against Stefanos Tsitsipas with a right leg injury.
Federer possibly sustained it by catching himself when he slid on a wet, slippery line.
With the rash of exits on the women’s side, Federer is the first on the men’s side out for health reasons.
Federer had plenty to say about the excessive watering to umpire Carlos Bernardes during that Coric match.
He also took a rare medical timeout for a blister.
