Hello and welcome to LIVE updates of French Open champion, Garbine Muguruza's second round clash with Slovakia's Jana Cepelova.

GAME, SET AND MATCH! - MUGURUZA 3-6 2-6 CEPELOVA. Jana Cepelova, the world 124, stuns French Open champion and number two seed, Garbi Muguruza with a straight sets demolition job in just 58 minutes. The Slovakian deserves it for her bold hitting against an out of sorts Spaniard.

MUGURUZA 3-6 2-5 CEPELOVA. Garbi asks the serve out question of Jana. The Slovakian gets to deuce but can't finish the job on the return and she must now forget what is at stake and just play like it's another game. If she does that, she'll pull off the biggest shock of the tournament so far....

MUGURUZA 3-6 1-5 CEPELOVA. Truly gutting for Mugu. She has three BPs but can't make any count. Jana gets out of jail from deuce when the Spaniard sizzles long once more. Surely that is her glimmer of hope gone?

Pretty much what we are all thinking, especially if you saw her in the French Open final.

MUGURUZA 3-6 1-4 CEPELOVA. Garbi finds her serve at crisis point and thunders her way to a love hold. She's on the board but it'll take something rather special to rescue this.

BREAK! - MUGURUZA 3-6 0-3 CEPELOVA. The French Open champion is on the ropes. She's broken again and is looking down the barrel here. She needs Cepelova to choke but the Slovakian is blitzing shots past her for fun.

MUGURUZA 3-6 0-2 CEPELOVA. Jana can sense this match is there for the taking and rattles through a confident hold to consolidate that break. Muguruza showing little emotion but clearly not on top form here.

BREAK! - MUGURUZA 3-6 0-1 CEPELOVA. This is looking like more than a blip to correct for Muguruza now. Cepelova grinds away at her opponent from 30-30 and claims the immediate breakthrough. A set and a break up. Are we looking at a major shock here?

SET! - MUGURUZA 3-6 CEPELOVA. A fantastic 29 minutes for Cepelova as she serves it to 30 with a blistering forehand. It's no more than she deserves as she has taken advantage of some surprising errors from the number two seed.

MUGURUZA 1-3 CEPELOVA. Garbi gets on the board with a hold to 30. It's been a poor start by her standards but there's plenty of time to turn this around.
