A stunning response set up a 7-6 (7-4) 6-3 success.
Simona went on to do some more shopping and picked up three gifts for her family members including perfume, headphones and baklava. "The most important is to go out there and focus and play every point like really focused".
"I don't know why I'm crying", she said. She been on top for long time.
"I've had many matches with her and won them". It was her third three-setter in four days and came about as much through sheer grit and determination as any superior groundstrokes or serves.
While Halep moved past round three, Kerber's tournament came to an abrupt halt against the unorthodox Hsieh.
Halep, a finalist in Doha last week, was supported even in the middle of a workday by scores of chanting, enthusiastic local Romanian fans, and her country's ambassador to the UAE, as she saw off Tsurenko in tricky conditions. I'm more relaxed. I don't put pressure on myself. The only absentees are No3 Sloane Stephens, who plays Acapulco next week, No10 Serena Williams, and No14 Caroline Wozniacki, who was forced to withdraw as she prepares to undergo medical tests for viral illness. I feel that my game is pretty strong, also physically, even if I'm exhausted a little bit.
"I feel close to my highest level".
Simona Halep's fine form continued at the Dubai Tennis Championships on Wednesday as she brushed aside Lesia Tsurenko, but fellow seed Angelique Kerber was sent crashing out. She was happy to once again emerge as the victor from a draining encounter.
"I have no idea how I won, I was thinking many times during the match points that I was already back in the locker room", said Bencic.
If Petra Kvitova does get her hands on the Dubai trophy against Belinda Bencic on Saturday, she will be quick to admit she did it the hard way.
"Second set I was slowing down a little bit, so it's not a good sign", said Hsieh. It was really hard to kind of find a way with it. I wasn't really that prepared for this tournament. "It's great when you're not playing your best and you still find a way to win".
That 62-minute win set up a meeting with Suarez Navarro following the Spaniard's 7-5 7-5 triumph over Kristina Mladenovic - who knocked out Osaka on Tuesday.
Tournament Director Salah Tahlak added, "We continue to see great drama and outstanding competition from not only numerous best players in the world but their less recognised opponents, and results remain unpredictable as we move closer to Saturday's climax".
The semi-final line-up for the Premier 5 event was confirmed on Thursday, with Bencic's battling victory over former world number one Simona Halep providing a highlight of the day's play.
