"This is the first time I have beaten the world number one, it is fantastic", said the world number 48 Hsieh after beating world number one Simona Halep.
It's the first time in the Open era that none of the top five women's seeds have made the last 16 of a Slam. "But still I'm sad about myself".
With that, the 32-year-old former doubles World No 1 became the first unseeded player to beat the top seed at Wimbledon since 2008, when Ana Ivanovic was beaten by Jie Zheng. But I am too exhausted, I was too exhausted, I have pain everywhere. "I'm very, very grateful and thankful about all this".
Top seed Simona Halep went out of Wimbledon in the third round after losing an epic three-set battle against Hsieh Su-wei.
In addition to knocking off Halep here, Hsieh has also upset Garbine Muguruza at the Australian Open and Johanna Konta at the French Open. Halep is a defensive counter-puncher first and foremost, using her excellent agility and court coverage to stay in points for far longer than virtually any other player on Tour would be able to.
These two have vastly different playing styles.
"I'm having a really good time at the moment". "The ball is not bouncing two times in a row the same". I am too exhausted. The two-handed technique inevitably makes it more hard for her to defend due to a limited reach, but her awkward style and ability to create angles that other players can't makes her a hard match up. She even hits her forehand strokes with both hands.More news: Belgium denied by 'small margins' in France defeat, says Martinez

Hsieh believes her sudden success is a result of playing with more confidence and freedom rather than worrying about failure.
Halep was a point from victory while ahead 5-4 as Hsieh served at 30-40. Who will come out on top? She threw everything she had at Hsieh - and was simply outplayed. Two games down in the third set I kept fighting.
"(It's) very positive to be already in the second week, winning three matches", said Nadal, who will retain his world No. 1 status on Monday. She will also force Halep to step in and dictate, perhaps more than the Romanian is comfortable with.
Halep, the French Open champion, looked like she would escape after forcing match point at 5-4 against serve in the third, but Hsieh rallied before breaking again en route to serving out the victory. But she was never rattled. I'm just realistic and honest. She fought for every point only to be undone by the crafty and unpredictable strokes Hsieh put across the net. "If I don't fight, I don't get through". The crowd, as it had throughout the final few games of the match, erupted and was shushed by the chair umpire.
Williams tweeted: "She took her first steps".
"I accept that it was an unprofessional attitude from me today". She's back looking for her eighth title at the tournament and reached the fourth round on Friday.
"If I am in the final, I prefer to face an easier opponent".
