Britain's Laura Robson has stunned ninth seed Li Na to advance to the fourth round of the US Open.
Robson, Ranked 88th in the world, beat her Chinese opponent 6-4, 6-7, 6-2.
It was a stunning display by the young Brit as she powered past the 2011 French Open winner.
The victory for Robson comes off the back of her win over three-time US Open winner Kim Clijsters.
She becomes the first British woman to make the fourth round at a grand slam since Sam Smith at Wimbledon in 1998 and the first in New York since Jo Durie 21 years ago.
Afterwards, Robson revealed her plan had just been to take on her shots.
"I knew if I kept sticking with her and playing my shots it might pay off and it did," she told Sky Sports 3.
"I had a few break points early on and I gave them up with average returning, so when I got a chance I knew I had to go for it.
"She's a great hitter so knew I had to go for it, I'm going to go back to the gym and try to recover for the next match."
Robson also put her stunning tournament so far down to her fitness levels.
"I've been injured loads in the past and this is my first time injury free. That's the biggest improvement and difference," she added.Reuse content
