Fourth-seeded Caroline Garcia of France advanced to the semifinals of the WTA hard court tournament in Guadalajara on Friday as ailing sixth seed Marie Bouzkova withdrew before their scheduled quarterfinal.
Garcia, 30, had fought through two tiebreak sets to edge Japanese qualifier Ena Shibahara on Thursday, snapping a three-match losing streak that included a first-round exit at the US Open.
Garcia next faces fifth-seeded Magdalena Frech of Poland, who beat Canadian teenager Marina Stakusic 6-4, 6-3.
Frech needed an hour and 44 minutes to get past Stakusic, who had saved four match points on the way to a second-round upset of top-seeded Jelena Ostapenko on Thursday.
Australian qualifier Olivia Gadecki was the first player to book a semifinal berth, seeing off Italian Martina Trevisan 6-2, 3-6, 6-1.
The victory puts Gadecki through to her first WTA semifinal. She had reached the quarters for the first time with victories over former US Open champion Sloane Stephens and second-seeded American Danielle Collins.
Gadecki will play Colombian Camila Osorio for a place in the final. Osorio defeated Russian Kamilla Rakhimova 7-6 (8/6), 6-2.
