Wawrinka *6-4 0-1 Federer
Three big serves from Roger Federer help him save more break points for Stan Wawrinka. Radio Roland Garros contributor Matt Cronin points out that the windy conditions might be troubling Federer, whose game can be easily interrupted by these conditions.
6-4 en 46'... S. Wawrinka vire en t�te ! #RG15 http://t.co/pmZVMAnlqE
Wawrinka 6-4 0-0* Federer
It's Stan Wawrinka who snatches the first set on Suzanne-Lenglen. He saves break point, sending Roger Federer running around the court, and he seals the set when the 17-time Grand Slam champion nets. All done and dusted in 46 minutes.
"Je suis tout de m�me contente car je me suis battue jusqu'au bout." G. Muguruza. #RG15 http://t.co/YJ79ZVyuOC
Stan v Roger
Did you know, this is the fifth Grand Slam meeting between Stan Wawrinka and compatriot Roger Federer? All of those previous meetings have been won by Federer, who also leads the head-to-head 16-2. They've also met twice before at Roland-Garros, in 2010 and 2011, with Federer winning both those meetings. But...
5th break for #Tsonga for 4-1. Will #Nishikori turn this match around or will the Frenchman run away with it? #RG15 http://t.co/YQt6KJM8MJ
Nishikori 1-6 1-4* Tsonga
These are tense times in Kei Nishikori's box as Jo-Wilfried Tsonga roars to the double break in the second set. Nishikori had plenty of time to close out break point but instead he shoves his forehand into the tramlines. The crowd are cheering it up but Tsonga is trying to stay focused, eyes closed.
Wawrinka prend l'avantage sur Federer : 3-2. #RG15 http://t.co/3xxkYyis3n
Wawrinka *3-2 Federer
Super-coach to Roger Federer, Stefan Edberg, is looking cool in his sunnies as he watches his charge hold serve. Edberg, by the way, was a finalist here in 1989 when he was beaten by the record-breaking teenager Michael Chang, who's now in Kei Nishikori's box.
The unforced errors keep piling up for #Nishikori (19); meanwhile, #Wawrinka strikes 1st vs. #Federer, breaks for 2-1. #RG15
Wawrinka *2-1 Federer
Roger Federer is having a sit-down and a think after being broken by Stan Wawrinka. The eighth seed absolutely motoring at the start of this match, firing a winner down the line for 0-30 and a backhand passing shot to seal the break.
"I'm very humbled and I'm very appreciative of the hard work of everyone else around me" #Ivanovic on her road to the semi's #RG15
Nishikori *1-6 0-2 Tsonga
Jo-Wilfried Tsonga is already up a break in the second set. Kei Nishikori is struggling to find any rhythm in this match so far. It's got to be intimidating playing Tsonga in front of a vocal home crowd on Philippe-Chatrier.
"I'm very, very thrilled. It's been a long road" @AnaIvanovic a very happy lady into the SF's #rg15 http://t.co/0D6sVGv7PH
Wawrinka *0-1 Federer
Roger Federer opens up the serving on Suzanne-Lenglen against his Swiss Davis Cup team-mate Stan Wawrinka. The Swiss eighth seed - that's Stan by the way - is already hitting at maximum pelt and pushes two break points on the Federer serve before the second seed holds. That's six minutes on the clock - settle in tennis fans.
"I'm so excited. It's tough to describe those feelings. It was amazing today and the first time [into the last four at Roland-Garros] as well. It was very windy out there and the balls were moving, so you had to be really ready." On her semi-final against Ana Ivanovic, she says: "I'm excited and ready."
Big day for @luciesafarova! She beats #Muguruza 7-6(3) 6-2 to reach her 1st SF here & move into WTA Top 10. #RG15 http://t.co/cdvdeFNkxo
Lucie Safarova into semi-finals
The Czech 13th seed, Lucie Safarova, backs up her shock win over defending champ Maria Sharapova with a 7-6 6-3 victory over Garbine Muguruza to reach the last four. Safarova books her place in style too, pounding a backhand winner down the line. A few more errors crept into Muguruza's game in the second set and that proved the difference.
All of the emotions! See @AnaIvanovic's post match celebration in the corridors of #Chatrier with her team. #RG15https://t.co/LUiHxeGQJ8
Muguruza 6-7 2-4* Safarova
Over on Court Suzanne-Lenglen, Lucie Safarova is now a break up against Garbine Muguruza. The Spanish 21st seed double-faulted for break point and handed it over with a forehand error. The Czech edging to the second Grand Slam semi-final of her career.
Les coups droits de Lucie Safarova sont redoutables ! #RG15
Nishikori v Tsonga
Kei Nishikori leads the head-to-head against Jo-Wilfried Tsonga 4-1. The French 14th seed is aiming to reach the French Open semi-final for the second time, following his run into the last four in 2013. Nishikori has already notched up his best French Open this season, reaching the quarters for the first time. But the Japanese does have big-match experience, finishing runner-up at the 2014 US Open.

Here come the chaps on Chatrier
Some last-minute stretches for Jo-Wilfried Tsonga before he is announced. The French 14th seed makes his entrance to cheers from the Chatrier crowd and he responds with a big grin. Kei Nishikori already has his serious game face on as he readies himself. Interesting spot, Jo is wearing a pastel-coloured friendship bracelet on his left wrist. A good luck charm?

"I don't know if I should feel really old or really happy. You guys are just amazing, I had great support." On the windy conditions: "It was really, really tough to play. I was just really happy to serve out the last game." On the huge support in her players' box: "For me it's vital. This is what you go back to in good and bad days."
Ana #Ivanovic est en 1/2 apr�s sa victoire 6-3 6-2 contre #Svitolina. #RG15 http://t.co/pegcqizYGU
Ivanovic into semi-finals
We have our first Roland-Garros semi-finalist - and it's the familiar face of Ana Ivanovic. The 2008 French Open champion is through with a 6-3 6-2 victory over Elina Svitolina, who was competing in her first Grand Slam quarter-final. We suspect we'll see more from the 20-year-old too. But for now, this is Ivanovic's first semi-final appearance at a major for seven years.
Lucie Safarova's tie-break experience at #RG15 pays off as she storms to the breaker 7-3. The Czech 13th seed grabs the opening set from Garbine Muguruza. But we don't expect this intense encounter to be over yet...
We're loving this big-hitting on Suzanne-Lenglen between Lucie Safarova and Garbine Muguruza. The Spaniard faced break points on her serve but keeps the pressure on Safarova, who pushes her forehand long to see Muguruza hold.
Broadcasting on the entertaining Radio Roland Garros, contributor Craig Gabriel reveals that Lucie Safarova told him she plans to open a coffee shop when she retires from tennis. The Czech added that she also plans to make the cakes herself.
After 39 minutes, Ana Ivanovic is one-set up against Elina Svitolina on Chatrier. A lovely drifted drop-shot at the net helps bring up set-point. There are fist pumps AND a thump of the chest for Ivanovic.
Ana Ivanovic is serving for the first set on Chatrier. Over on Lenglen, Lucie Safarova and Garbine Muguruza are locked in a very intense seventh game, which has seen the longest rally of the match so far - 21 strokes all told.
Lucie Safarova is having to do some stern defence on her service games as Garbine Muguruza is beginning to dominate play from the baseline. The Czech 13th seed holds in the sixth game but only when the Spaniard pumps her forehand long.
Having squandered her own service game with a double fault, Ana Ivanovic is back a break in front against Elina Svitolina. The Serbian seventh seed is being watched closely by her footballer beau Bastian Schweinsteiger, who gives a wink. Although it might just be a blink in the bright Parisian sunshine...
Very strange watching the scoreboards tick over in the first game of our quarters, as exactly the same thing was happening on both showcourts! Ana Ivanovic and Garbine Muguruza held serve after being taken to deuce.
Yikes! We're a little behind the players but let's do our own handshakes over the virtual net of Blog HQ. I'm Sarah Holt, your Blog mistress for the next few hours. Get in touch by tweeting me @sholtscribbles or have your say @rolandgarros.
Over on Lenglen, Garbine Muguruza and Lucie Safarova are sizing each other up for the first time, having never met before on the Tour. Muguruza has never reached a major semi-final before while Safarova reached the last four at Wimbledon in 2014. Safarova, the 13th seed, has played eight sets here at #RG15 and four of them have been tie-breaks, Will she go the distance again today?
We open with an intriguing encounter on Chatrier between Ana Ivanovic,
the seventh seed and Elina Svitolina, seeded 19th. Since winning the
title here in Paris in 2008, Ivanovic has never gone as far as a
semi-final of a Grand Slam again. Svitolina has achieved her best
result at a major by reaching the last eight at #RG15. The 20-year-old
has nothing to lose now.
A sneak peek at Lenglen now reveals that Roger Federer - aiming to reach the semi-finals at Roland-Garros for the first time since 2012 - is sparring with Frenchman Tristan Lamasine as he gets in some practice ahead of the looming Swiss showdown.
Ana Ivanovic, the winner here in 2008, has the honour of being the only former female champion left in this side of the draw after defending champ Maria Sharapova fell to a shock exit yesterday at the hands of Lucie Safarova. If you'd forgotten how that match played out by the way, you can catch up with Matt Trolllope's report.
Hands up if you're ready for some #RG15 quarter-finals! Well, you're in luck because we are getting closer to the business end of the ball striking here at Roland-Garros. There are four quarter-finals this afternoon sprinkled with spice. Stay with us.
So, our female defending champion Maria Sharapova is out, Serena Williams hangs tough and Rafael Nadal and Novak Djokovic make a last-eight date. Our #RG15 quarter-finals are settled and they begin tomorrow. Let's meet back here for a 2pm start. Au revoir!
The word on the street is that there are now three Swiss players into the French Open quarter-finals for the first time. Guess what? Roger Federer and Stan Wawrinka - the top Swiss chaps - will be back on Suzanne-Lenglen tomorrow to fight for a place in the semi-finals..
There is a huge shout of "Allez Timea". The Swiss fans in the crowd sensing a victory for their top female player. Petra Kvitova drifts the ball into a net on a forehand and then she doubles the error by hitting wide. Timea Bacsinsky is into the quarter-finals of Roland-Garros.
Timea Bacsinszky has already reached a new Grand Slam high by reaching the fourth round in Paris. She's now ranked as the world No. 24 after breaking into the top-50 for the first time at the end of 2014. According to the WTA bible, she also has two dogs and two cats. So now you know.
Petra Kvitova screams as she gets on the board at the start of the third set. She had to fight off break points to do it by the way. It's a much easier service game for Timea Bacsinszky as she holds to love.
A fan with a Swiss flag laid over their legs can raise it in celebration as Timea Bacsinszky, the Swiss No.1, wraps up the second set without losing a single game to Petra Kvitova. She seals it with an ace by the way.
In case you didn't know, Petra Kvitova gained the nickame P3tra in 2013 because of her propensity for getting herself into three-set matches. She finished that year with a sparkling 25-9 record when her matches went the distance. Timea Bacsinszky now has a 4-0 lead in the second, so we could be heading that way once again.
Over on Suzanne-Lenglen, Timea Bacsinszky forces an early break against Petra Kvitova. The Czech pushes her to 0-40 in the next game. Kvitova defends from behind the baseline but pushes a forehand long for deuce. Bacsinszky holds to consolidate.
"I'm not worried about running out of gas. You know, I'm 33. I'm not going to play another 10 years, so I better not run out of gas now. I'm not going to quit. "You know, it's why stop now? I'm going to keep going as hard as I can until I'm out. And, you know, if that means I have to go another nine sets, then so be it. But nothing's going to make me run out of gas in terms of that"
By the way, Rafael Nadal leads the head-to-head against Novak Djokovic 23-20. They've only met once this year in the semi-finals in Monte Carlo, and Djokovic ran out a straight sets winner. When they meet again on Wednesday it will be Nadal's 28th birthday. So, um, happy birthday?
We're see-sawing over on Suzanne-Lenglen. Petra Kvitova and Timea Bacsinszky swapped breaks in the opening exchanges but another double-fault and a long forehand sees the Wimbledon champion move ahead once more.
Revenge is sweet for Serena Williams as she defeats fellow American Sloane Stephens, who shocked her at the 2013 Australian Open. But the world No.1 says she feels like she's living on the edge in Paris. Matt Trollope reveals the whole story in his report for roland-garros.com
There's still plenty of people strolling around Roland-Garros, enjoying the late evening sunshine. Large screens around the grounds are also zoomed in on Petra Kvitova and Timea Bacsinszky's fourth-match. A pair of double-faults and a netted forehand from the Swiss hand Kvitova the break at 3-1 in the opening set.
The men's quarter-finals at #RG15 are complete. Let's have a look at the match-ups...Kei Nishikori  v Jo-Wilfried Tsonga Stan Wawrinka  v Roger Federer Novak Djokovic  v Rafael Nadal Andy Murray  v David Ferrer Tomas Berdych, seeded four, is the only one of the top-eight not to make it through to the last, well, eight. He lost to Jo-Wilfried Tsonga.
Before doing a quick signing session, Novak Djokovic says of his quarter-final with Rafael Nadal. "I am excited about the match. It's a very big challenge. I hope it will be a good match." Remember he's speaking in French there and this is the Blog HQ translation!
Novak Djokovic sets a date on Wednesday with Rafael Nadal in the #RG15 quarter-finals. His vanquished opponent Richard Gasquet goes to sign a few autographs for waiting fans after a match that lasted exactly two hours. Novak Djokovic tells the crowd that it was a very good match and it was difficult for him to play a Frenchman on Philippe Chatrier.
On Chatrier, Novak Djokovic wastes little time recovering the break from Richard Gasquet, taking it when the Frenchman misjudges a forehand and sends it long. The world No.1 is serving for the match now.
"It's a very tough match. I know Novak today is the best player in the world so to have any chance against him I have to play my real best tennis and that is what I'm looking forward to."In French he adds that Paris is his home and that he hopes to have the fans behind him when he plays in the last eight.
Rafael Nadal fires himself into the quarter-finals of Roland-Garros where he is poised to meet Novak Djokovic. The Spanish nine-time champion takes time to collect himself after the match, tying his shoelaces and toweling himself down. It was probably tougher against American Jack Sock than he would have liked.
On court right now, Rafael Nadal and Novak Djokovic are moving closer and closer to their highly-anticipated last-eight meeting. Rafael Nadal moves into a 5-2 lead in the fourth set when Jack Sock misses an attempted forehand smash at the net. Over on Chatrier, Nole has a 4-1 lead in the third set against Richard Gasquet.
The frustrations are beginning to show for Richard Gasquet. Once again he saves break points against Novak Djokovic, but the eight-time Grand Slam champion pushes him into an error of the forehand and that's the break.
Rafael Nadal is fired up on Suzanne-Lenglen. He grits his teeth and comes back from 0-40 down to hold. By the way, John McEnroe, a finalist here in 1984, is watching from the stands as is Sock's sometime doubles partner Nick Kyrgios. Remember you can read about that bromance here.
Over on Chatrier, Richard Gasquet saves two more break point against Novak Djokovic. It's a must-win set for the Frenchman. We are well into the evening here in Roland-Garros but we still have lovely sunshine and a great atmosphere on our show courts.
Novak Djokovic snuffs out more Richard Gasquet's break-back chances with a backhand down the line. He's looking comfortable as he retakes his seat. By the way, the Serbian has a 10-1 head-to-head record over his French peer. Both aged 28.
Radio Roland Garros contributor Matt Cronin says Richard Gasquet needs to take a lesson from Jack Sock as he continues to toil against Novak Djokovic on Chatrier. "He's just got to hang in there and hope," he says.
Court Suzanne-Lenglen is the place to be right now. Jack Sock is in inspired form as he breaks Rafael Nadal to 15 to push this match into a fourth set. How did he do it? With a whipped backhand down the line for 15-40 and a forehand winner on set-point. It's the first set that Rafa has lost at #RG15 so far.
There's no let-up for Jack Sock in his first meeting with Rafael Nadal. The American does well to break Nadal only to lose his serve to love. Blog HQ is now working collectively on our Sock puns. "Sweaty Sock wrung out" our best effort so far... OK, we'll go home soon.
Richard Gasquet is hustling against Novak Djokovic but his flighted play cannot match the power of the world No.1. Djokovic lifts a lob for set-point and closes it out when the Frenchman puts the ball long.
