Johanna Konta is already eyeing a spot in the US Open final after reaching the last eight for the first time in her career.
The 28-year-old recovered from a set and a break down to beat former finalist Karolina Pliskova 6-7 (1-7) 6-3 7-5 at Flusing Meadows.
It looked like the Czech was going to run away with the tie but Konta had won 16 of her 19 three-set matches this year and battled back to improve that record.
The British number one is now the first British woman to reach the quarter-finals since Jo Durie 36 years ago and will face Ukrainian fifth seed Elina Svitolina or American 10th seed Madison Keys in the last eight.
“I’ve reached the fourth round for the first time and to go one step further is a massive achievement for me,” she said.
“I’m hoping to go one or two more steps better than that.”
"The key was to keep going, with Karolina you know there will be massive portions of the match where I don't feel effective.
"It is about staying out there and trusting the fundamental things. It was a great match and I'm so happy."
Konta received great encouragement from the New York crowd and has now reached the last eight in all four Grand Slam tournaments.
Pliskova had previously won six of their seven tour-level meetings but some impressive groundstrokes brought along 45 winners - enough to finally see Konta over the line.
