Paris: Former World No. 1 Caroline Wozniacki was left "frustrated" after collapsing to a 0-6, 6-3, 6-3 loss to Russian World No. 68 Veronika Kudermetova in the French Open first round yesterday and told her opponent she "got lucky".

The Danish 13th seed had retired injured from her two previous matches in the lead-up to Roland Garros, but looked to have found form in a one-sided opening set. Last year's Australian Open champion lost her way in the second set, though, making 10 unforced errors, but said her opponent was fortunate to turn the match around.
