Rafael Nadal comes out on to Philippe Chatrier wearing a luminous orange/pink marker bandana with matching mask.

He means business.

The Czech superstar beat Oceane Dodin 6-3 7-5 to reach the second round.

Liam Broady is really holding his own in this second set against Jiri Vesely. He dis not dwell on losing that first and is taking the Czech on.

Crucial moments now, though, as he's serving to stay in the set.

Cheers Michael. Grand work.

This will be done in three, right?

Champion Rafael Nadal is going for a 13th title and bidding to equal Roger Federer's record of 20 Grand Slam singles crowns.

He's opens his campaign against Belarusian Egor Gerasimov.

They've never met, until now.

Time to pass you on to Saj Chowdhury to talk you through Egor Gerasimov versus Rafael Nadal.

Serena Williams says: "It's really nice to be here, it's different.

"Not so many people but it's nice to have a few people and in the last few tournaments there was nobody so it's nice.

"In the first set it was not easy and I played very well, I made a lot of winners. I had to concentrate to win and stay very focused for the second set."

Czech 15th seed Marketa Vondrousova will not be be repeating her run to last year's women's final after she was defeated by 6-1 6-2 by Pole Iga Swiatek at the first-round stage.

Vondrousova struggled with her serve, producing five double-faults, and struggled at the net, winning only 31% of points.

Ahn opts for a drop shot but it doesn't have enough legs and Williams with a fifth match point.

A forehand goes long and Williams, after having four match points, is having to save a break point. But a cross-court backhand is wide. Deuce.

An ace brings match point number four, but Ahn is clinging on.

Williams has just wasted three match point chances.

Williams with an overhead smash and Ahn is facing a second set bagel. Match points

Ahn goes long and she has fallen apart in this set. Williams a set up and 5-0 up, serving for the match.

A tasty drop shot from mid-court from Williams is too good and Ahn, stretching forwards can't flick it over the net. Williams then produces a great forehand winner and two more break points.

Liam Broady is fighting hard on court 10 - he finally managed to carve out a break point on the Jiri Vesely serve in the third game of the second set.

But after four deuces the Czech held firm.

Still, the Briton has got to be encouraged by the pressure he put on his opponent there.

The first set lasted 74 minutes. Only 16 minutes in set two and Williams is 4-0 ahead and Ahn is looking drained and out of ideas.

Earlier on (see 14:11 entry) we mentioned Mats Wilander questioning whether Andy Murray should be given wildcards to tournaments.

That got an unhappy response from Australia's Nick Kyrgios.

Now world number 16 Karen Khachanov is not too impressed with Kyrgios' tweet.

We're in the final straight now and Serena Williams is closing in on the finish line and round two.

She gets a double break. There's not much emotion shown from Serena but there only looks one winner from now on.

Williams is threatening to steamroller through this set. She sees two break points come and go though - one a backhand return into the net and a second a winning drop shot from Ahn with Williams at the back of the court.

Now the former world number one has a third chance though.
