British No. 1 Cameron Norrie reaches the Los Cabos Open final after beating Felix Auger-Aliassim 6-4 3-6 6-3 in Mexico.
Defending champion Nori next faces world No. 1 Daniel Medvedev, who beat Serbia’s Miomir Kekmanovic.
It was Norrie’s first win over his Canadian opponent, where he hit 17 aces compared to the Briton’s two.
British duo Emma Raducanu and Dan Evans suffered losses in the quarterfinals of the Washington Open.
“Felix got me the last four times, so I really wanted to win that one,” Norrie said.
“I had match point before, so I had this in my head. It’s not going to be easy.”
His next opponent, Russian Medvedev, played in his first match since June after injury – and Ban Russian players at Wimbledon.
But it will be his fourth final since beating Kekmanovic 7-6 (7-0) 6-1.
That means he will play at this month’s U.S. Open — where he’s the reigning men’s singles champion — to secure the world number one.
Meanwhile, in Washington, defending women’s US Open champion Radukanu was defeated 7-6 (8-6) 6-1 by Russia’s Lyudmila Samsonova.
After Samsonova saved four sets in the first set, the world number 60 overtook the British teenager in the second set.
Radukanu, 19, hopes to reach her first semifinal since winning a major last year.
Samsonova will face China’s Wang Xiyu in the semifinals, where the 21-year-old defeated two-time Australian Open champion Victoria Azarenka.
The other semi-final is Estonia’s Kaia Canepi against Australia’s Daria Saville.
Meanwhile, Britain’s No. 2 Evans was beaten by Japan’s Yoshihito Nishioka in the quarterfinals 7-6 (7-5) 4-6 7-5.
It was the pair’s fifth meeting — Nishioka won all five.
Nishioka will face top seed Andrei Rublev in the semifinals. Russia’s Rublev played two games on Friday in a crowded schedule delayed by rain, but prevailed over Americans Maxime Cresci and JJ Wolff.
Australia’s Wimbledon runner-up Nick Kyrgios faces Sweden’s Mikael Immel in the other semifinal.
