World number one Ashleigh Barty is out of Wimbledon after her defeat to Alison Riske in the fourth round.
The Australian, who rose to the No 1 spot after her shock victory at the French Open, had been in fine form after a sensational 15-match winning run.
But Barty was brought down to earth with a thud by Riske, who reached her first-ever Grand Slam quarter-final at the 30th attempt and at the age of 29.
The 23-year-old, having taken the opening set against the unseeded American, was stunned as 55th-ranked Riske fought back to win 3-6, 6-2, 6-3.
Barty began well, serving four straight aces in the opening game on her way to winning a 21st successive set over the last three tournaments.
Yet Riske, who had spent more than four hours longer on court than Barty in the first week, dug-in for a trench battle, out-slugging Barty to take the next two sets.
She could potentially face seven-time champion Serena Williams in the last eight, with the 37-year-old taking on 30th seed Carla Suarez Navarro on No. 1 Court.
