Taiwan`s Hsieh Su-wei pulled off another stunning upset to reach the semi-finals of the Dubai Duty Free Tennis Championships on Thursday, when she staged a remarkable late rally to beat fourth seed Karolina Pliskova 6-4, 1-6, 7-5.
The unseeded Hsieh, who knocked Wimbledon champion Angelique Kerber out of the last 16 on Wednesday, was on the ropes at 5-1 down in the deciding set against the big-serving Pliskova, but won the last six games to deny the Czech victory.
Hsieh will battle Pliskova`s compatriot, two-times Wimbledon champion Petra Kvitova, for a place in Saturday`s final after the second-seeded Czech despatched Slovakian Viktoria Kuzmova 6-4 6-0 in a one-side quarter-final lasting 62 minutes.
Kvitova, who was champion in Dubai in 2013 and runner-up at this year`s Australian Open, sent down 21 winners and won 74 percent of her first serve points while making 12 unforced errors as she dominated from start to finish.
"I didn`t give (Kuzmova) any time to do her job, maybe turn the match in her way," Kvitova said after the win.
"(Hsieh is) a tough and tricky opponent. I played her in Sydney in a really tough match. Will be probably some rallies tomorrow, and I need to be ready for every shot she`s going to bring to the game."
On the other side of the draw, unseeded Swiss youngster Belinda Bencic ousted world number two Simona Halep 4-6, 6-4, 6-2 in a seesaw quarter-final.
Bencic, ranked 45th, broke Halep`s serve seven times during Thursday`s contest before claiming victory on her third match point as her Romanian opponent ran out of steam.
The 21-year-old will face defending champion Elina Svitolina in the other semi-final after the Ukrainian eased past Spain`s Carla Suarez Navarro 6-26-3 in the day`s last match.
