Tokyo (AP) — Wimbledon champion Garbine Muguruza advanced to the semifinals of the Pan Pacific Open by beating Caroline Garcia 6-2, 6-4 Friday.
A rare double-fault by the top-seeded Muguruza allowed Garcia to pull even at 3-3 in the second set, but the Spaniard broke back in the next game.
Playing in her first tournament since earning the No. 1 ranking, Muguruza will next face Caroline Wozniacki. The former top-ranked Dane advanced when Dominika Cibulkova was forced to retire with a right thigh injury while trailing 3-6, 7-6 (5), 3-1.
Also, Angelique Kerber upset second-seeded Karolina Pliskova 7-6 (5), 7-5. The seventh-seeded Kerber took advantage of several unforced errors by the Czech player and won with a powerful cross-court shot on her fifth match point.
Kerber will face Anastasia Pavlyuchenkova in the semifinals. The Russian beat Barbora Strycova 5-7, 6-3, 6-1.
