PARIS – Former world number one Petra Kvitova is out of the French Open after being stunned 7-6 (8-6), 7-6 (7-4) in the third round by Estonia's Anett Kontaveit on Saturday.
Despite saving two match points, the two-time Wimbledon champion Kvitova fell as Kontaveit overpowered her in both tie-breaks.
Meanwhile, US Open champion Sloane Stephens battled past Italy's Camila Giorgi after dropping the first set to win 4-6, 6-1, 8-6.
Kvitova, the Czech eighth seed, trailed 5-3 in the first set and even though she battled to force a tie-break, Kontaveit's punishing ground strokes were too much to handle as the Estonian snatched the advantage.
A consistent backhand gave Kontaveit two chances to serve out the match but Kvitova fought back again in determined rallies, only to run out of steam in the deciding tie-break and a desperate forehand, while facing three match points, landed long and confirmed her exit.
Earlier on Philippe Chatrier, third-seeded ex-champion Garbine Murguruza eased past Australia's Sam Stosur 6-0, 6-2 in 62 minutes to secure her place in the fourth round.
However, in the men's event, French home favourite Lucas Pouille was beaten 6-3, 7-5, 6-3 by Russia's Karen Khachanov.
