Kiki Bertens reached the third round of Roland Garros on Wednesday in a sensational match.

The fifth-placed Dutchman made a lot of mistakes against Italian Sara Errani, who herself did not reach too high a level, but eventually won.

On track fourteen in Paris, Bertens won 7-6 (5), 3-6 and 9-7 in a match with no fewer than 24 breaks against the Roland Garros finalist of 2012, who is now 150th in the world ranking.

Bertens played a lousy match.

She made a lot of unnecessary mistakes in the second and third set and played into the hands of the experienced Italian, who ran on almost every ball.

Errani caused quite a stir in the first two sets with poor service.

She often failed to throw the ball properly in the air, was penalized for taking too much time and sometimes opted for an underhand serve as an alternative.

In the next round, Bertens faces the winner of the confrontation between Anastasia Pavlyuchenkova from Russia and Katerina Siniaková from the Czech Republic.

Bertens starts again below par

Just like in her first round match against the Ukrainian Katarina Zavatska, Bertens did not start well on Wednesday.

She gave up her first two servicings against Errani, who took a 3-0 lead.

Not much later, the Dutch number eight in the world faced a 5-2 deficit and seemed to have to give up the set, but straightened up and started to take advantage of Errani's bizarre service.

She forced a tiebreaker, in which she was narrowly the strongest: 7-5.

The changeable Bertens - she increasingly alternated nice points with painful misses - also had a hard time in the second set against the energetic Errani, who started to serve a little better.

A break at a 4-3 deficit meant a set win for the Italian.

In the second part of the third set it rained breaks back and forth, with the visibly frustrated Bertens getting injured and looking anything but fit.

She seemed to be heading for a defeat, but still managed to break at 7-7 and hit her fourth match point.
