Britain's Katie Boulter backed up the biggest win of her career by beating Caroline Garcia to reach the Birmingham Classic quarter-finals.
The day after defeating Alison Riske for her first win over a top-40 player, Boulter triumphed 7-6 (7-5) 6-1 over French former world number four Garcia.
Garcia double-faulted to lose the first set and was still unhappy early in the second, with Boulter taking advantage.
"I'm absolutely ecstatic right now," Boulter, 25, said.
She will next face either compatriot Harriet Dart or former world number one Simona Halep, who are playing later on Wednesday.
