Katie Boulter’s reign as the queen of Nottingham is over after she lost in the quarter-finals to McCartney Kessler.
Boulter was gunning for a third successive Nottingham Open crown, having won in 2023 and 2024, but came unstuck against the world number 42 with victory in sight.
The British number two was 4-3 up with a break of serve in the final set, but lost the last three games, including her serve twice, to go down 6-3 3-6 6-4.
That saw her 12-match winning run on her home court come to an end.
American Kessler said: “It was a really tight match, it was close. I wanted to stay within myself and keep playing my game and luckily I came out on top.
“We are both aggressive players, so there was a lot of shot-making.
“I am trying to get as many titles as I can and put myself in the position to win titles. I am looking forward to the rest of the weekend.”
She will play Rebecca Sramkova in Saturday’s semi-finals.
Dayana Yastremska will play Magda Linette in the other semi-final.
Ukrainian Yastremska beat former US Open finalist Leylah Fernandez 6-3 7-6 (6) in the quarter-final.
Linette downed top seed Clara Tauson 6-2 7-5 to book her spot in the last four.
