STUTTGART, Germany — Maria Sharapova advanced to the semifinals of the Porsche Grand Prix by beating Anett Kontaveit, 6-3, 6-4, on Friday.
In her third match following a 15-month doping suspension, Sharapova converted five of her six break points.
Sharapova, who tested positive for meldonium at last year’s Australian Open, will next face 19th-ranked Kristina Mladenovic on Saturday.
Kontaveit had only five unforced errors in the first set, but Sharapova broke for a 4-3 lead and won the next two games. She broke early in the second set, too, and then again for a 4-2 lead.
