Qinwen Zheng staged a second epic comeback at the US Open in as many days to stun former champion Iga Swiatek and book her place in the quarter-finals for the third time.
Two days on from overturning a 5-0 third-set deficit against Madison Keys, Zheng mounted another remarkable fightback on Arthur Ashe, recovering from 5-0 down in the opening set.
A stunned Swiatek never recovered, and the 2022 champion succumbed in straight sets, 7-5 6-3, leaving the court in tears after her campaign unravelled in unthinkable fashion.

Zheng, the former world No 4, has come through qualifying after being sidelined by a long-term elbow injury and can now set her sights on a last-eight showdown with either Naomi Osaka or Elena Rybakina.
Zheng revels in being back on big stage
"I started the match not so well but I found my rhythm," Zheng said.
"It has been a long, long time since I played on a centre court and I really appreciate being here on Arthur Ashe Stadium.
"I took it point by point and little by little I started to play better and find my game.
"I even forgot the score at 4-5 in the first set, which showed I was focused. To come back from 0-5 is not lucky, that's all I can say."
'One of the great comebacks'
Sky Sports Tennis' Jonathan Overend:
"It's a straight-set win but it's one of the great comebacks. Go figure. How's that possible? Zheng made it happen.
"Two games in a row, 5-0 down in sets. She got the win against Madison Keys to gets the first set today to complete victory against Swiatek for the only the second time in her career.
"The Chinese dream lives on as the qualifier makes it into the final eight."
