Paula Badosa fell victim to a knee injury and was forced to quit her Roland Garros third round match, handing a 6-3, 2-1 win to Veronika Kudermetova on Saturday.
The Spanish third seed took a medical timeout in the second set but never looked like being able to make a match of it.
While the physio massaged her troublesome joint, the WTA No. 4 covered her head with a towel, occasionally raising it to reveal a glum expression.
Kudermetova advanced to the second week in 68 minutes, with 17 winners, 17 unforced errors and three breaks of her ailing opponent.
Kudermetova earned a fourth career win over a Top 5 player with now-retired No. 10 Kiki Bertens her most illustrious victim before beating Badosa.
