Johanna Konta took her second match point to beat Karolina Pliskova 7-6(1), 6-3, 7-5 and reach the quarter-finals of the US Open for the first time. Konta broke Pliskova early in the first set, but the Czech fought her way back into it, preventing the Brit from serving it out, and then dominating the tie-break 7-1. But the British number one regrouped for the second set, winning five games on the spin to force a decider. The third set proved to be incredibly tight, but Konta got the decisive break in the penultimate game to allow her the opportunity to serve for the match, and an encounter in the next round with either Elina Svitolina or Madison Keys. This is the first time Konta has reached this stage of the US Open – and her Slam third quarter-final in a row. "I've been in the fourth round twice before so reaching the quarter-finals is a massive achievement for me," the British number one said after the match. " 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." She is the first British woman to reach this round since Jo Durie – 36 years ago.
