Maria Sharapova breezed into the semifinals of the Tianjin Open with a comfortable straight sets victory against Swiss qualifier Stefanie Voegele.
The former world No. 1 and five-time Grand Slam winner took just over an hour to win 6-3, 6-1 in China.
Sharapova lost her first service game but fought back to draw level before going on to take the opening set with a hold to love.
Voegele presented Sharapova with three match points when she made her eighth double fault when serving at 5-1 down and the Russian sealed the match with a forehand winner.
Sharapova -- targeting a first title since returning to the tour in April following a drugs ban -- will face third seed Peng Shuai of China after she thrashed Sara Sorribes Tormo 6-0, 6-1.
In the other quarterfinal tie, Aryna Sabalenka beat local hope Lin Zhu 6-3, 6-4 and she will play Sara Errani.
