SOFIA, Bulgaria (AP) Carla Suarez Navarro advanced to the semifinals of the season-ending Tournament of Champions by beating Tsvetana Pironkova 7-6 (2), 6-1 on Friday.
The fifth-seeded Spanish player was under pressure knowing that only a straight-set victory would secure her spot in the semis.
Home favorite Pironkova tried hard but failed to convert two set points at 6-5 in the tiebreaker. Suarez Navarro took a quick 5-0 lead in the second set and allowed Pironkova just one game before clinching the set and her required victory.
