Australia’s world number one Ashleigh Barty has been knocked out of Wimbledon, losing her fourth-round match against American Alison Riske.
Barty, who began Manic Monday on a run of 15 consecutive victories, was widely tipped to add the Wimbledon crown to the French Open title she won in June but an error-strewn performance on Court No2 allowed Riske to spring a surprise.
World number 55 Riske fought back from a set down to win 3-6 6-2 6-3 in one hour 36 minutes on court two to reach a first Grand Slam quarter-final.
Riske, unseeded and ranked 55th in the world, is a surprise winner but she has showed her form here already, coming from a set down to overcome the 13th seed Belinda Bencic in the previous round.
French Open champion Barty, 23, had not dropped a set at the tournament.
Riske will face the winner of seven-time champion Serena Williams’ match with Spain’s Carla Suarez Navarro.
“I couldn’t begin to say what it means to me. To have overcome the matches the way I have is what I’m most excited about,” said Riske, 29.
“Getting to the quarter-finals is amazing but what’s most exciting for me is the way I’ve been fighting.
“The grass definitely brings out the best in me. Hopefully it will rub off and happen in other places too. I think my game is just well suited to it.”
