KEY BISCAYNE, Fla. (AP) - Li Na became the first Chinese woman to reach the Key Biscayne semifinals when she beat Caroline Wozniacki 7-5, 7-5 Wednesday at the Sony Open.

Li's opponent Thursday will be Dominika Cibulkova, who erased three match points in the second set - one when a call was overturned via replay - and beat Agnieszka Radwanska 3-6, 7-6 (5), 6-3.

The No. 2-seeded Li won the Australian Open in January and is 20-2 this year. She has a 6-0 career record against Cibulkova.

Six-time champion Serena Williams will play five-time runner-up Maria Sharapova in the other semifinal.
