MIAMI - China's Li Na rolled over Caroline Wozniacki in straight sets to reach the semi-finals of the WTA Miami tournament, where she will face Dominika Cibulkova in an rematch of the Australian Open final.
Second seeded Li posted a 7-5, 7-5 win over 11th seeded Wozniacki while Cibulkova saved three match points in a gritty three-set victory, 3-6, 7-6 (7/5), 6-3, over third-seeded Agnieszka Radwanska on the hardcourts at Crandon Park.
The 10th-seeded Cibulkova will break into the top 10 in the world rankings for the first time on the strength of her victory.
"I knew before the match that this was the match I needed to win to become top 10," Cibulkova said. "So it was some more pressure, but I'm obviously very happy with the way I handled it today." Cibulkova, who is in the Miami semi-finals for the first time, is winless in six career meetings against Li.
Li beat Cibulkova in the Australian Open final, and also won the rematch in the quarter-finals at Indian Wells earlier this month.
"So many people think about this being a repeat of the final, but it's not," Li said. "Because Australia is over. It is past already. Miami is Miami. I am just looking forward for tomorrow." The other semi-final had already been set, with world number one and defending champion Serena Williams due to take on fourth-seeded Russian Maria Sharapova.
American Williams defeated Sharapova in last year's final to capture a sixth Miami title, sending Sharapova to her fifth loss in five finals.
Cibulkova, who swept past Radwanska 6-1, 6-2 in the semi-finals of the Australian Open, had a bigger fight on her hands on Wednesday on a windy Stadium Court where service holds were at a premium.
Fourteen of the first 18 games of the contest were breaks of serve, with Radwanska finally fending off three break points to hold serve for a 5-4 lead in the second set.
The world number three from Poland had three chances to seal the match in the next game - most dramatically at 30-40 when her blistering service return was judged long only after a challenge by Cibulkova.
