Britain's Jo Konta puts her surprise US Open run down to being able to enjoy the pressure after working on the mental side of her game.
Konta beat 18th seed Andrea Petkovic 7-6 (7-2) 6-3 to reach round four, after converting her sixth match point.
Konta, ranked 97th, had previously won just one Grand Slam main-draw match.
"I think the main thing is I'm just really enjoying the situation, even when I lost I don't know how many match points," said Konta.
