Upsets at Wimbledon reached a zenith on Saturday at the All England Club when more than half of the seeds in play were defeated by unseeded players, including the toppling of the world No. 1.
The latest was fourth-seeded Alexander Zverev, who lost to the qualifier Ernests Gulbis, 7-6 (2), 4-6, 5-7, 6-3, 6-0.
"I didn't think I could win after losing the third set, but he got exhausted and I played smarter", added Gulbis.
In the men's singles, No. 2 seed Rafael Nadal eased into the fourth round as he swept Alex De Minaur 6-1, 6-2, 6-4, continuing his clean record so far. Cunning drop shots, often played with two hands on the racket, delicate slices and laser-like flat groundstrokes that hugged the turf kept Halep off balance. "It is magical to play in front of the unbelievable fans here".
"I just try to enjoy the tennis and enjoy the city, enjoy the food", said the 32-year-old.
Elise Mertens, seeded 15th, was knocked out 6-2 6-2 by Johanna Konta's conqueror Dominica Cibulkova. I just want to feel free and enjoy the match. I enjoy everything here - the strawberries, the shops, everything.
"I was too exhausted".
Now only No. 7 Karolina Pliskova remains among the Top 8 seeds.
Halep failed to carry on the momentum, and a huge forehand victor gave Hsieh the first break of the second set and a 2-1 lead.

Cheryshev collected the ball near the halfway line, exchanged passes with Artem Dzyuba and curled a 25-metre shot past Subasic. The teams then went back and forth in regulation, and neither could find the victor , sending the game into extra time.
The result ensures the Spaniard will retain his number one crown at the end of the tournament.
"I knew what to expect, we played a lot of tough battles in the past", Kerber said of Osaka.
Asked what she planned to do next she said: "Anything but tennis".
"I just believe that I was not very positive on court", Halep said.
Jelena Ostapenko, the 2017 French Open champion, also went safely through after she swept aside Vitalia Diatchenko in straight sets.
Making her fourth appearance at Wimbledon, Ostapenko will look to improve on her run to the quarter-final past year.
Milos Raonic (13), Canada, def. Dennis Novak, Austria, 7-6, 4-6, 7-5, 6-2.
However, Djokovic eventually got the break he needed after a misfired half-volley from Edmund before clinching the match on serve with an ace after two hours and 54 minutes.
