Britain’s Lily Miyazaki seals first slam win by defeating Betova at US Open

• World No 198 is lost for words' after 6-3, 6-3 triumph
• Iga Swiatek cruises to victory; Holger Rune is knocked out

Lily Miyazaki has spent much of her professional career on the lower levels of the ITF circuit, usually fighting tooth and nail in front of no more than a couple of committed spectators. The goal has always been to continue rising and, eventually, to settle at the top level of her sport. She has never been closer.

After qualifying impressively for a grand slam main draw for the first time, Miyazaki took a significant step forward as she clinched her maiden win at a major by beating Margarita Betova of Russia 6-3, 6-3.
