Nottingham Open: Katie Boulter beats Sonay Kartal to reach quarter-finals, Mimi Xu beaten

Katie Boulter had to dig deep to beat Sonay Kartal in an all-British tie and keep her bid for a third straight Nottingham Open title on track.

Boulter trailed in the deciding set and almost went a double break down before regrouping to win 6-4 1-6 7-5 and reach the quarter-finals.

Eighth seed Boulter also called for the doctor during the match after struggling with the hot weather.

“I am definitely proper British because I can’t handle the heat at all,” the 28-year-old said.

“I’m just glad I got over the line.”

Boulter is on a 12-match winning streak in Nottingham, having won her first WTA Tour title in the city two years ago.

The Englishwoman will now face American McCartney Kessler for a place in the last four.

“I feel like I step into my house when I come on to this court. I have such great vibes here,” Boulter said.

Boulter is the last Briton in the women’s singles after Welsh teenager Mimi Xu was beaten by Poland’s Magda Linette earlier on Thursday
