British teenager Isabelle Lacy claimed the biggest win of her fledgling career by knocking out third seed Madison Brengle at the Lexus Surbiton Trophy.

The 16-year-old came through qualifying and overcame a rankings gap of more than 750 places to see off American Brengle 7-6 (2) 5-7 6-1.

Brengle has been as high as 35 in the world and, although aged 33 she is now down at 95, this was a hugely impressive performance from Lacy, who already has a wild card into Wimbledon qualifying courtesy of winning the British Under-18 title.

A few more performances like this one may just see that upgraded to a full wild card.

Dan Evans took a wild card into the men’s event after his first-round loss at the French Open and he joined Andy Murray in round two with a 6-4 6-4 victory over Australian James McCabe.

Katie Boulter and Katie Swan were both convincing winners on the women’s side – Boulter beating Olivia Gadecki of Australia 6-2 6-1 while Swan saw off Canada’s Carol Zhao 6-2 6-0.

Eden Silva and Sonay Kartal also reached round two but Heather Watson was edged out 2-6 7-6 (3) 7-6 (6) by Australian Maddison Inglis and there were losses for Mark Whitehouse, Billy Harris, Dan Cox and Harry Wendelken on the men’s side.
