Women's round-up: Bertens beats Parmentier to continue fine form on clay

The Dutchwoman lifted the title at the Mutua Madrid Open earlier in May without dropping a set, and made it to the semi-final of the Internazionali BNL D'Italia in Rome the week afterwards.

Twin of one of the tournament favourites, Kristyna Pliskova was knocked out in the first round of the French Open by Lauren Davis.

The Czech player - sister of former world number one Karolina - lost in straight sets 6-2 6-4 to the American.

There was an early upset on Court 1 as Germany's Julia Goerges, seeded 18th, crashed out to Kaia Kanepi 7-5 6-1. The Estonian has reached the French Open quarter-finals twice before and looked on fine form during her straight-sets win.

Australia's Ashleigh Barty - who could be a dark horse for the title after her rise up the singles rankings this year - needed just two sets to defeat Jessica Pegula, winning 6-3 6-3.

Croatian Donna Vekic defeated Ludmilla Samsonova in two sets, 6-2 6-4, while French player Alize Cornet could not hold out in her home tournament as she lost 6-4 6-3 to Viktoria Kuzmova.

And Anastasija Sevastova, who beat Luksika Kumkhum of Thailand, will next take on Luxembourg's Mandy Minella, who vanquished Anastasia Pavlyuchenkova.
