Kerber broke serve three times in the first set and rallied from 3-1 down in the second, clinching victory when the Russian hit a forehand long. Klara Zakopalova of the Czech Republic also advanced, rallying to beat sixth-seeded Julia Goerges of Germany 3-6, 7-5, 6-1. Zakopalova, who reached her first semifinals since the Korea Open last September, will next face second-seeded Marion Bartoli of France or Roberta Vinci of Italy. Zakopalova won seven straight games in sealing the second set and taking a 5-0 lead in the third. She ended the match when the German hit a forehand return long. Goerges took a medical timeout at 4-0 in the final set to have her left thigh massaged. She initially broke for a 2-0 lead and took the first set when Zakopalova netted a forehand. But Zakopalova evened the match when Goerges dropped serve at 6-5, hitting a forehand that caught the tape before dropping out.
