Ashleigh Barty's Wimbledon campaign is over following a disappointing, mistake-riddled third-round loss to Russian Daria Kasatkina.
Barty made a flying start before collapsing to a 7-5 6-3 defeat at the hands of the 14th seed on Friday.
Her coach Craig Tyzzer was left shaking his head in dismay as the 17th seed piled up 24 unforced errors to bow out in the first week of a grand slam for the 15th time in as many appearances.
"A frustrating day for sure," Barty said.
"It's disappointing to lose in any tournament, but I felt like I was playing well and I wasn't able to do that today.
"I knew what I wanted to do out there but I wasn't able to do that."
Barty had boasted the most grass-court wins of any player on the women's tour heading into the match but, with a place in the second round of grand slam for the first time beckoning, the 22-year-old's execution deserted her.
"I felt like my slice wasn't as effective as I wanted it to be. Couldn't put it in the positions of the court that I wanted to," she said.
"It was just generally frustrating day, a tough one to swallow."
Barty looked on course to become the first Australian-born woman to make the last 16 at The All England Club in 18 years after charging to a 3-0 lead.
The former Wimbledon junior champion broke Kasatkina at the first opportunity and held her first two services games to love.
The tide began to turn when, aided by a lucky net cord winner, the Russian broke back in the seventh game before levelling the first set up at 4-4.
Barty's second ace gave her a 40-15 lead when serving at 5-5 but three backhand errors and a beautiful lob winner from Kasatkina suddenly earned the Russian a second break out of nowhere and a 6-5 advantage.
The 14th seed served the first set out as the errors continued to flow from Barty.
Kasatkina claimed her third break in the fifth game of the second set but Barty hit straight back only to falter again from 40-15 up.
The Aussie No.1 double-faulted then dumped a forehand in the net before surrendering to lose the match in just 73 minutes.
