Petra Kvitova weathered a mid-match fight back from Samantha Stosur to reach her third final from the last four tournaments she has taken part in at the China Open on Friday.
The in-form Czech, who has won all matches since her third round exit at the US Open, outlasted the Australian 6-3 5-7 6-2 to reach her fourth championship final of the year.
She will face second seed Maria Sharapova in her first appearance in the China Open final. The Russian fourth seed saw off Ana Ivanovic 6-0 6-4 in the other semi-final of the day.
The 3rd seed raced through the first set in 44 minutes, but Stosur rallied back hitting 13 winners to just nine unforced errors in the second set.
Kvitova stepped up her game in the decider reeling off five games in a row from 1-2 to finish off the contest.
“It’s tough to say something about the match,” said the Wimbledon champion. “I mean, it was really up and down. In the second set she was the better player on the court.
“I’m just glad I could win it in the third. I knew how Samantha can play really well, and she played a really amazing second set. I was a little bit worried in the third set, like if she continued playing that way, it could have been a pretty quick one.
“But I had some chances and I did it. In the end I served well, and that was important.”
After winning at the All England Club in July, the 24-year-old triumphed in New Haven and Wuhan. A fourth victory in Beijing will see her equal her career-high ranking of No. 2- leapfrogging WTA rising star Simona Halep.
