MELBOURNE, Australia – Li Na advanced to the Australian Open semifinals for the third time in four years, bringing fourth-seeded Agnieszka Radwanska’s 13-match winning streak to a shuddering halt.

Sixth-seeded Li, who lost the 2011 Australian Open final to Kim Clijsters only months before her Grand Slam breakthrough at the French Open, had a 7-5, 6-3 victory over Radwanska in the first match Monday (Tuesday in Australia) on Rod Laver Arena.

“She’s a tough player. I was feeling today against a wall,” Li said. “She can hit everywhere, but without a mistake. I was feeling just very tough. You have to focus on every shot. Not every point, every shot.”
