Stojsavljevic – who is part of the Loughborough University National Tennis Academy (LUNTA) – powered past her opponent to claim a stunning maiden Grand Slam title at Flushing Meadows.

The 15-year-old Londoner produced a performance that showed maturity beyond her years to dispatch Japan’s Sonobe in straight sets.

A euphoric Stojsavljevic sank to her knees after being confirmed champion. Her name will now be etched into the US Open history books alongside previous winners Lindsay Davenport, Marion Bartoli, and Victoria Azarenka.

The last British person to win the Girls’ title at the US Open was Heather Watson in 2009.

“I’m super happy and super grateful,” Stojsavljevic said.

“Thank you to my family for supporting me back home and to the crowd here; you’ve been great.

“It was quite nerve-wracking, I had to trust my serve and treat it like any game. I like fighting, it’s so fun to compete and play every match. When you win it’s such a great feeling.

“I feel I have handled myself pretty well. I had some tough matches. I lost the first set in the first round but stayed as strong mentally as possible.”

Elsewhere, LUNTA graduate Mingge Xu was edged out at the semi-final stage by eventual finalist Sonobe, 6-4 6-4.

Stojsavljevic’s victory is LUNTA’s second major title in just over 12 months following Henry Searle’s Boys’ title at Wimbledon in 2023.
