US Open live: Pegula v Krejcikova latest score before Venus Williams in doubles action

After failing to convert break point in the last game, Pegula is broken by Krejcikova to get the first set back on serve. This is a bad game for Pegula to give away, too, making a double fault on 15-15 followed by forehand and backhand errors.

Krejcikova is serving under 50 per cent and it’s giving Pegula a lot of looks on the returns. The American brings up another break point but Krejcikova saves for the second game in a row to hold and stay in touch.

Pegula is lasering the ball in the early stages and pushes for the double-break. Krejcikova roars as she saves with an ace down the middle.

A rotten start for Krejcikova, who was under pressure from Pegula as the American found a forehand winner to move to 0-30.

Krejcikova then misses an overhead, appearing to lose the track of the ball in the sun, and double-faults when facing the first of three break points.

The US Open quarter-finals kick off with last year’s runner-up Jessica Pegula against former Wimbledon champion Barbora Krejcikova.

Krejcikova, who is also a US Open doubles champion, saved eight match points in her win over American Taylor Townsend in the previous round.

Pegula has enjoyed a fairly straight-forward run so far, she is one of only four players to record more than 40 wins this season after Aryna Sabalenka, Iga Swiatek and Elena Rybakina.

Krejcikova leads the head-to-head 2-1 against Pegula.
