On a rainy day at the French Open, Timea Bacsinszky, the 30th seed Swiss, reached the women’s semi-finals with a 6-4, 6-4 win over local 13th seed Kristina Mladenovic. It is the second time that Bacsinszky has made it to the semis here. The 27-year-old player will now play unseeded Latvian Jelena Ostapenko, who stunned Danish 11th seed Caroline Wozniacki 4-6, 6-2, 6-2 for a place in the semi-finals.
