Move on Stan, nothing to see here. No change for Wawrinka as Tsonga rattles through a service hold to love. Anyone fancy another tie-break?
More drama than an episode of Eastenders in this game. Break points are casually tossed between the pair in deuce, with boos raining down on Wawrinka as he challenges a line call at 40-40. And it is a good job the Swiss does, because he is spot on. The ball was out by the width of piece of string. Wawrinka takes advantage, prompting Tsonga into a colourful exchange with his box. "Life is beautiful!" he says as he tells his coaching staff and support to calm down. Then the Frenchman loses the point and the game.
What a match this is. Djokovic v Murray? Pah.
Wawrinka, who like Tsonga is aiming to reach his second Slam final, battles back from 30-0 down to level before handing over a break point to the Frenchman.
This is a potentially pivotal point in this match. But, in a familiar pattern to this match, Tsonga can't convert. He has made just 10% of his break points, with Wawrinka faring marginally better at 20%. On we go...
Piers Newbery
BBC Sport at Roland Garros
"While French hopes rise by the minute with the rejuvenated form of Tsonga, much of the discussion courtside centres on the best source of Parisian weather forecasts.
"There are terrifying tales of a biblical storm heading our way, with Roland Garros set to be battered by hail within the hour, while others suggest a quick storm will roll over nearby Longchamps and leave us well alone. For now, it's hot, sunny and all is well."
This is a survival of the fittest. Tsonga is half a yard ahead going down the back straight of the third set, I'd suggest, holding his serve with much more comfort than Wawrinka. Two game points for the Frenchman, who bounds up to the net to volley into a winning position, Wawrinka only finding the net with a scrabbling backhand.
Image source, EPATsonga, slapping his racquet and waving his hands upwards, signals to the French crowd. "Louder," he urges. "Louder."
Like a crowd at an indie gig transfixed by the gaiting frontman, Court Philippe Chatrier responds to his call. Tsonga responds by going 30-30 before Wawrinka restores calm with his 10th ace of this sweltering afternoon.
Momentum is gone for Tsonga, whose loose forehand completes a hold for one-time Slam winner Wawrinka.
Stephen Frew: , externalHere's hoping these two can continue to batter each other to give Murray an easy final after his straight sets victory later. #bbctennis
Lee: , externalOnly one man can beat Stan Wawrinka and that's Stan Wawrinka
Hashim:, external The Wawrinka backhand down the line is a majestic piece of art. That shot could win him the tournament.
Stan Wawrinka is not feeling 100% fit and requires some more medical treatment at the change. Not exactly sure what the problem is, but it must be linked to that troublesome middle finger which was strapped up earlier.
The Swiss has no answer to Tsonga's serve in the sixth game of the third set, the Frenchman cruising to a hold to love.
Image source, APBoom! Tsonga ups the ante with a rasping forehand from the baseline that a stretching Wawrinka can only dream of returning. Stan resumes composure to move 40-15 ahead and that should be that.
But wait! Tsonga finds his inner Paul Daniels, pulling a magic flick of the backhand out of a wide position, past Wawrinka and to safety. Brilliant. However, the Swiss star tightens his grip on the game in the next point.
Image source, AFP/GETTYAfter that brief - and well-earned - delay, we're back up and running. Tsonga has the ball in his hand, smashing his way to 15-0 and then forcing Wawrinka into a rogue forehand. The Swiss responds with a brilliant backhand winner down the line for 30-15, only to go wide with a crosscourt effort with the next. Wawrinka has no answer to a big Tsonga serve and that is game over.
Image source, APWhile Wawrinka has some cream applied and a bandage wrapped around his digit, Tsonga uses his time wisely - to have a snooze. At least that's what I imagine he is doing as he closes his eyes for a few moments. He wouldn't be going through some visualisation techniques would he...
Image source, ReutersStan Wawrinka has a problem. The Swiss eighth seed has asked for the trainer at the change of ends, looks like he is having the middle finger on his right hand strapped up. Nothing too serious I wouldn't imagine.
Court Philippe Chatrier is rocking! That's because Tsonga slips, slides and blasts his way to two break points.
Oh my! What a backhand volley from Wawrinka to save the first. That's not from the top drawer - it's from the secret compartment where you only go to on special occasions....
The crowd must have a sudden bout of laryngitis - it has lost its voice. Probably because Wawrinka has silenced them with a dazzling array of shots to rescue the second break point and then clean up in deuce.
Image source, Getty ImagesAny disappointment from being unable to convert that last game into a break is not evident. The Tsonga serve is singing, reaching all the high notes as Wawrinka finds himself woefully out of tune in a hold to love.
Tsonga wastes that opportunity, then splutters over another break, leading to a shriek from the Frenchman. He has missed nine of the 10 break points coughed up by Wawrinka. The Swiss knocks the pendulum back in his own favour, forcing Tsonga into a wild backhand to concede the game.
Wawrinka's head appears to be still in the locker room, the eighth seed starting slowly with a gloomy backhand and a miserable double fault. But the Swiss earns a slice of luck when a forehand clips the tape, forcing Tsonga to readjust to return, but leaving Wawrinka with the equivalent of a conversion in front of the posts. However, another double fault hands an early break chance to Tsonga...

Image source, AFP/GETTYSwiss star Wawrinka, looking rather hot and bothered, remerges first to a generous round of applause before Tsonga jogs out seconds later. The Frenchman tightens his shoelaces on an advertising board and then we are ready to resume...
