TOKYO (AP) -- Second-seeded Caroline Wozniacki of Denmark rallied from a set down to beat qualifier Jarmila Gajdosova of Australia 4-6, 7-5, 6-3 Thursday to advance to the quarterfinals of the Pan Pacific Open.
The U.S. Open finalist broke Gajdosova three times in the third set at Ariake Coliseum and won with a crosscourt backhand. She will take on eighth-seeded Carla Suarez Navarro of Spain in Friday's quarterfinals.
''She played a great game and it took me a while just to get into it,'' said Wozniacki , who won the tournament in 2010. ''I managed to pull through today and was a little bit lucky but also played some good points at important moments.''
Suarez Navarro defeated Daria Gavrilova of Russia 7-6 (5), 6-3.
Also, Garbine Muguruza of Spain defeated fourth-seeded Jelena Jankovic of Serbia 7-6 (4), 6-4 and will face Casey Dellacqua of Australia in the quarterfinals. Dellacqua beat Marina Erakovic of New Zealand 6-2, 6-4.
