World number one Ashleigh Barty reached the Wimbledon quarter-finals for the first time with a straight-set victory over Barbora Krejcikova.
The Australian defeated French Open champion Krejcikova, making her first Wimbledon singles main draw appearance, 7-5 6-3.
She will face British wildcard Emma Raducanu or compatriot Ajla Tomljanovic in the last eight.
"It was an incredibly tough match," Barty, 25, said.
"Barbora has had an incredible year, she's been one on the toughest players to beat.
"I get my confidence from all the work I put in behind the scenes. This is the fun part.
