Konta takes quarter-final spot, Watson loses battle of Brits

Johanna Konta kept up her hopes of winning the Nottingham Open for the first time as the British number one beat Kateryna Kozlova to book a quarter-final berth.

Top seed Konta had to bounce back from a disappointing second set to claim a 6-2 1-6 6-3 win over the Ukrainian, and will now face Alison Van Uytvanck in the last eight.

The 30-year-old Konta, who has twice reached the final of this event, split from her coach following a disappointing first-round exit from the French Open.

In Nottingham, she will be joined in the last eight by Katie Boulter, a 7-6 (7-4) 6-3 winner over fellow Briton Heather Watson.

Alison Riske, the American second seed, could be Boulter's next opponent. Riske was required to play twice on Thursday, firstly when completing a match against Wang Xiyu that began on Wednesday.

Following that gruelling 3-6 7-5 7-6 (7-3) win, which secured a first WTA singles victory for Riske since last year's US Open, the 30-year-old returned to the court against compatriot Lauren Davis and they were tied at one set each when play was suspended for the day.

Third seed Donna Vekic slipped to a 6-3 6-4 defeat against Nina Stojanovic, who will play Tereza Martincova next.

The other quarter-final will see Kristina Mladenovic – a winner over Caty McNally – take on Zhang Shuai.
