Australia’s world number one Ashleigh Barty has been knocked out of Wimbledon, losing her fourth round match against American Alison Riske.
World number 55 Riske fought back from a set down to win 3-6 6-2 3-6 in one hour 36 minutes on court two to reach a first Grand Slam quarter-final.
French Open champion Barty, 23, had not dropped a set at the tournament.
Barty set the early tone as she took the opening game with four successive aces, before a delightful sliced back-hand set up break-points as the Australian raced into a 4-1 lead.
Unshaken, 29-year-old Riske – who won the pair’s only previous meeting in 2016 – brought the set back on serve, only for the world number one to take the final two games and pocket the opener in 32 minutes.
The American rallied in the second set, breaking Barty twice more as the momentum was swiftly stolen away from the Australian.
And, despite losing just 12 games in her opening three matches, Barty was unable to prevent a resurgent Riske continuing her best Wimbledon run as the American made a crucial break at 4-3 in the deciding set.
