Mika Stojsavljevic ensured there was British success at the US Open as she became the junior champion.
The 15-year-old Londoner beat Wakana Sonobe 6-4 6-4 to become the first Briton to win the girls' tournament in New York since Heather Watson in 2009.
Stojsavljevic followed up her impressive semi-final display, where she ousted Iva Jovic - the 16-year-old American who made it to the second round of the main women's draw - with another assured performance.
It came 24 hours after Jack Draper's semi-final defeat in the men's draw and shows the future of British tennis is looking bright.
While Stojsavljevic claimed glory, Mingge Xu was a beaten semi-finalist, as was Charlie Robertson in the boys' tournament.
"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."
She added: “I think I’ve handled myself pretty well this week.
“I’ve had some tough matches, I lost the first set in the first round. Staying as strong as mentally possible has been the biggest thing for me.
