*Murray 2-6 1-1 Nishikori
Wife Kim is watching on from the stands. She must be used to this by now. She'll know not to get too worried at this early stage.
On the court Murray gets to 40-0 but then gets a backhand all wrong. He looks down to the clay and shakes his head. Not happy with the surface or his foot movement, one or the other.
Nishikori is hitting with real depth. He pegs Murray back to deuce.

*Murray 2-6 1-1 Nishikori
Murray looks a little late in moving to the Nishikori groundstrokes.
Maybe that is a sign of him not as sharp as he can be but more a reflection of the power the world number nine is playing with.
Both the Nishikori forehand and backhand are looking strong. He takes the game with little fuss.

Murray 2-6 1-0 Nishikori*
Come on Andy. Good start needed here.
Things are looking a little tricky at 30-30 but the big first serve bails out Murray. More of that please.
"Come on," he shouts.
That's better. Murray battles and battles to keep himself in the point, forcing Nishikori to hit one more ball. The Japanese player puts a smash wide and Murray stops the rot.

*Wawrinka 4-2 Cilic
Image source, Getty ImagesWhile Andy Murray is in a spot of bother on Chatrier, there are no such problems for Stan Wawrinka. Not yet anyway.
Stan IS the man in the opening stages of his quarter-final against seventh seed Marin Cilic.
The Swiss third seed goes a break up in the second game and is ahead over on Lenglen.

Murray 2-6 Nishikori
Barry Flatman
Sunday Times tennis correspondent on BBC Radio 5 liveThe good thing is that Andy Murray can switch from Plan A to Plan B quickly. There are a few players in the game who can't do that but it is one of major reasons he is the world number one.
Murray has to be more dominant. He has to dictate to Nishikori, where as Nishikori is dictating to him.

*Murray 2-6 0-0 Nishikori
That was a very impressive set of tennis from Kei Nishikori.
A little strange because Murray looked good in the first couple of games but then the eighth seed just motored away from him.
10 winners for Nishikori in the set, compared to just five from Murray. The Briton has also hit 10 unforced errors. Three more than his opponent.
Who's going to win it?published at 16:03 British Summer Time 7 June 2017
Pliskova 7-6 (7-3) 6-4 Garcia
Image source, Getty ImagesBasically we have no idea who is going to be lifting the Coupe Suzanne Lenglen on Saturday.
What we do know is that it will be a first-time Grand Slam champion.
And we know it will one of Halep, Karolina Pliskova, Latvian teenager Jelena Ostapenko or Swiss 30th seed Timea Bacsinszky.
Halep will play Pliskova in the last four, after the Czech second seed beat Caroline Garcia 7-6 (7-3) 6-4 in Wednesday's other quarter-final.
Garcia, 23, was the last French hope remaining in both the men's and women's singles draw. Zut alors!

BBC Sport at Roland GarrosAn absolutely stunning, potentially career-defining, win for Simona Halep over Elina Svitolina. The Romanian third seed and favourite appeared set to miss out once again on a first Grand Slam title as she was overpowered by Ukraine's Svitolina for an hour-and-a-half.
However, Halep saved a match point and powered through the final set like a champion in waiting, with the world number one ranking also there for the taking if she wins the title.

Halep 3-6 7-6 (8-6) 6-0 Svitolina
Sensational scenes over on Lenglen!
Simona Halep is considered by many as the favourite to win the women's singles - and here's why.
The Romanian has battled back from a set and 5-1 down to beat Ukraine's fifth seed Elina Svitolina in the quarter-finals.
Halep won five consecutive games and then saved match point to take it to a decider, which she finished off with ease.

Murray 2-6 Nishikori
Nishikori is hitting a harder ball but is also more consistent than Murray at the moment.
These are worrying signs for Murray. It all changed after those two double faults in the third game.
The Japanese player takes the set with a glorious drop shot. Murray didn't even move.

And Nishikori only needs one of them!
What a start from the Japanese player. He now leads with two breaks in this first set and will now serve for it.

Murray puffs his cheeks as another backhand winner goes past him.
Danger. Lots of it. Nishikori comes to the net to set up two break points...

*Murray 2-4 Nishikori
Murray is trying to get into a Nishikori service with some heavy returns but for now at least the Japanese player is holding strong.
Here are a couple of errors from Nishikori. First a poor drop shot and then a forehand long. He looks annoyed with that. 30-30.
Now two winners from Nishikori. Murray didn't do a lot wrong there. Good play from his opponent.

BBC Sport at Roland GarrosHunched forward, hands clasped together, steely gaze - Ivan Lendl has gone up a gear with his player-box body language today, this must be a big match. There's more movement in the stands between games as spectators return after watching home hope Caroline Garcia bow out. Pat Cash briefly interrupts the Murray service motion in his role as courtside reporter. Everyone just settling down.
