Johanna Konta enjoyed one of the biggest wins of her career by beating third seed Karolina Pliskova to reach the quarter-finals at the US Open.

The British No.1 from Eastbourne dropped the first set on a tie-break but battled back to win 6-7 (1), 6-3, 7-5.

In doing so Konta became the first British woman to reach the last eight at Flushing Meadows since Jo Durie in 1983.

Konta had lost six of her previous seven matches with Pliskova, including twice on her home turf of Devonshire Park, as well as in Nottingham and Birmingham.

None of those defeats will matter now with Konta continuing her fine season in the grand slams with a third successive appearance in a quarter-final.

She said: "I'm really pleased because, like my first round, every match is difficult in its own way.

"But I know that, like with everyone, there's always going to be certain players or certain types of game styles that are just more difficult for each player to play against.

"Obviously my record shows that I find it difficult to play against Karolina. I'm just pleased I was able to basically just find a way and enjoy being out there, knowing that nothing was for certain.

"I could have lost that match just as easily as I would have won it so I'm pleased overall at how I stayed out there and played."
