Mika Stojsavljevic became the first Briton in 15 years to win the US Open girls' title as she beat Wakana Sonobe in New York.

The 15-year-old cruised to a 6-4 6-4 victory over Japan's Sonobe.

It is a first Grand Slam title for the junior, with her previous best run coming in 2023 when she reached the quarter-finals at Wimbledon.

She is the first British girl since Heather Watson in 2009 to win the title at Flushing Meadows.

"I'm super happy and super grateful," Stojsavljevic said.

"Thank you to my family for supporting me back home and thank you to the crowd here, you've been great."

Stojsavljevic saw off third seed American Iva Jovic, who made it to the second round of the main women's draw, in Friday's semi-final.

She began playing tennis around the age of five at Ealing Lawn Tennis Club and cites five-time Grand Slam champion Maria Sharapova as her tennis idol.

In April, Stojsavljevic beat two-time Wimbledon quarter-finalist Tamira Paszek on her way to winning the W35 Nottingham ITF singles title.
