Defending women's champion Elena Rybakina lost in the Wimbledon quarter-finals as Ons Jabeur avenged her defeat in last year's final.
Sixth seed Jabeur came from a set down to win 6-7 (5-7) 6-4 6-1 in a reverse of the match 12 months ago.
The Tunisian clinched the second set with a timely break of serve at 5-4 and then dominated the decider.

Belarusian second seed Sabalenka beat the American 6-2 6-4 - keeping alive her quest to win a first Wimbledon title and replace Iga Swiatek as world number one.
In the men's draw Spanish top seed Carlos Alcaraz is through to the semi-finals for the first time and will face Russian third seed Daniil Medvedev in the last four.
Alcaraz beat Danish sixth seed Holger Rune, another 20-year-old, 7-6 (7-3) 6-4 6-4 in his quarter-final.
Unseeded Chris Eubanks' dream run was ended by 27-year-old Medvedev in a five-set contest.
Medvedev, who had never been past the last 16 before, beat the American 6-4 1-6 4-6 7-6 (7-4) 6-1.
Now Alcaraz and Medvedev - who have both won major titles on the US Open hard courts - will attempt to reach their first finals on the Wimbledon grass when they play in the last four on Saturday.
