Serena Williams has to dig deep to seal victory over a spirited Victoria Azarenka. The top seed wraps it up with a break on a fiery cross-court forehand. In her on-court interview she says that Azarenka played very well and how she had to talk herself into staying in the match.
Serena Williams is a game away from a place in the fourth-round. The American world No.1 has won five straight games to get herself in this position. She is gaining her composure at the changeover but can Victoria Azarenka raise a final fight?
Jack Sock is into the fourth-round at #RG15 where he'll meet Rafael Nadal. But for the young American tennis is not his whole world - find out why in Roland-Garros.com reporter Kate Battersby's feature.
Fact fans, you might like to know that the last time Victoria Azarenka played at Roland-Garros she reached the semi-finals. That was in 2013. The Belarusian didn't play here last year because of a foot injury.
Serena Williams - after sportingly pointing out that a ball by Azarenka that was called out was in fact good - breaks the Belarusian on the very next point. Azarenka stalks off with her bag for a bathroom break. The atmosphere is building at Philippe-Chatrier now.
There was a double serving of Special K in Paris this morning, Roland-Garros.com reporter Kate Battersby has been finding out about the two Australians with a hunger for serial success. You can read all about it in her special feature.
Ana Ivanovic (Srb)  v Ekaterina Makarova (Rus)  followed by Kei Nishikori (Jpn) v Teymuraz Gabashvili (Rus) Stan Wawrinka (Sui)  v Gilles Simon (Fra)  Lucie Safarova (Cze)  v Maria Sharapova (Rus) 
Here's an interesting fact. Serena Williams split with her long-time hitting partner Sascha Bajin earlier this year. He's now sitting in Victoria Azarenka's box. I'd say Bajin is a useful addition to Azarenka's team.
We kick-off the fourth round at #RG15 tomorrow! Here's the run-down for Philippe-Chatrier:Elina Svitolina (Ukr)  v Alize Cornet (Fra)  followed by Jo-Wilfried Tsonga (Fra)  v Tomas Berdych (Cze)  Gael Monfils (Fra)  v Roger Federer (Sui)  Flavia Pennetta (Ita)  v Garbine Murguruza (Esp) 
Her Fed Cup team-mate Serena Williams might be struggling but Sloane Stephens has sailed into the fourth round. Her plans for tomorrow? "Hang out with my team and do a whole bunch of nothing," she says.
As many tennis experts were predicting, things remain tight on Philippe-Chatrier between Serena Williams and Victoria Azarenka. Williams has a bit of a coughing episode at the changeover. A few players sniffly this week.
"Being in the fourth round without losing a set and playing solid and consistent, that's what I need to do. Then I arrive the second week and you have to go that extra step to have chances. I hope to have a good practice tomorrow and be ready to play a great match on Monday, because I will need it."
Sloane Stephens can't serve it out but she can do it with another break against Tsvetana Pironkova. The American is into the fourth-round for the fourth year running. "I'm playing really solid, I'm happy to be back," says Stephens.
Meanwhile over on Suzanne-Lenglen, Sloane Stephens is serving for the match. As we mentioned before, Tsvetana Pironkova has a heavily bandaged left thigh so we wonder if that might be affecting her today.
It's still very busy and bustling out on the grounds at Roland-Garros. The queue for the waffle stand is six-deep. Everyone refuelling and stretching their legs for the final match of the day on Chatrier, Serena Williams v Victoria Azarenka. The players are knocking up now.
Fine celebrations from Richard Gasquet. First he fires over a winner at balle de match, falls flat on his back in relife, and then he jumps up in the air and pumps his fist. The Frenchman is through, knocking out 15th seed Kevin Anderson. Gasquet thanks the crowd afterwards for their incredible support.

Pironkova *2-4 Stephens
After swapping breaks early on, Sloane Stephens is a break up against Tsvetana Pironkova. The Bulgarian has her left thigh heavily wrapped up, by the way. Stephens, the world No.40, has reached the fourth round in Paris for the last three years.
Are you worried you've missed Murray or forget your rendezvous with Rafa? Then fear not because Courtney Nguyen has been following the favourites so you don't have to. All you need to do is read her round-up for Roland-Garros.com.
Simone Bolelli has ditched the camouflage top for a bright orange one - maybe he wants to blend in with the clay now? Across the net, David Ferrer has found another level and is racing towards the fifth set and the match.
"A common human being with a very unsual life." That's three-time French Open champion Gustavo Kuerten's take on his tennis tale as he returned to Roland-Garros on Saturday. Our reporter Matt Trollope went to find out more and you can read all about Guga's return.
#Gasquet holds for 7-5. The Frenchman leads big serving #Anderson two sets to one. #RG15 http://t.co/DjcGDbZA8Z
Gasquet 4-6 7-6 7-5 0-0* Anderson
The cheers from Philippe-Chatrier filter over to Blog HQ because Richard Gasquet has just taken a two-sets-to-one lead over Kevin Anderson. The Frenchman is hoping to reach the fourth round for the fourth time.
And the man, who is on course to meet Novak Djokovic in the quarter-finals, has once again proved his form on the clay. Rafael Nadal is being bombarded with chants of "Rafa, Rafa" by young fans wanting his autograph after a straightforward win over Andrey Kuznetsov.
Yikes! We forgot to tell you that Rafael Nadal is into the third set now hoping to close it out against Russian Andrey Kuznetsov. Just as a reminder, Nadal is trying to become the first person in the Open Era to win 10 titles at any Grand Slam event.
"Je suis très heureuse d'avoir géré la pression." A. Van Uytvanck #RG15 http://t.co/GmEV3eeoSp
Gasquet 4-6 7-6 0-0* Anderson
Is Richard Gasquet going to put the French fans on another rollercoaster ride? He came through five sets against Carlos Berlocq to reach the third round. For now, he's levelled this match against Kevin Anderson, winning the tie-break 7-4.
Easy does it for Jack Sock. The American has surpassed his best Grand Slam performance by reaching the fourth round of #RG15. Sock has knocked out teenage sensation Borna Coric but worth remembering Sock is only 22 himself!
A spot of Saturday afternoon practice for @rogerfederer #RG15 http://t.co/gUqaBUmipR
Over lunch at Suzanne-Lenglen, I was loving the build-up to Rafa Nadal's entrance. The announcer lists all his achievements and then ends his spiel saying he's a nine-time French Open champion AND then listing all the years to whoops from the crowd. Rafa then interrupted his warm-up to wave to the spectators.
Our fourth-round in the women's singles competition here at #RG15 is almost settled. Just two more names to add to the pot. It will be one of top seed Serena Williams or Victoria Azarenka and one of Tsvetana Pironkova or Sloane Stephens.
Bolelli wins his 1st set EVER over Ferrer, levels the match up at a set a piece. Nadal continues to cruise, wins 9 of 1st 10 games. #RG15
Change of ends
Thanks to one of the esteemed scribblers here at Blog HQ who stood in for me while I tucked into a plate of colorful tomatoes before taking a peek at Rafael Nadal. I'm Sarah and let's have a look around the courts and I'll then tell you a bit about Rafa.
2013 runner-up @DavidFerrer87, who is 5-0 H2H vs Italy's #Bolelli, currently leads 6-3 0-3 in their 3R meeting. #RG15 http://t.co/0LmnNm86iL
Easy does it for Rafa
No problems for Rafa, who takes the first set and loses just one game along the way. Novak Djokovic may be the favourite here, but Nadal is certainly looking very impressive. One of our writers, Matt Trollope, thinks Rafa is still the overwhelming favourite.> READ MORE: Nadal still the undeniable favourite
A big off-forehand winner, and Anderson has pocketed the opening set against local hope Gasquet on Chatrier. Anderson's height and weight of shot are actually quite well-suited to clay - it explains why he's won more matches here than at any other major. He reached the fourth round the past two years

Around the showcourts ...
Big cheers for Rafa as he enters Lenglen for his third-round match against Russia's Andrey Kuznetsov, while it's on serve early in the match on Chatrier between Gasquet and Anderson - the Frenchman and the South African are locked at 2-2 in the opening set.
Comfortable win for German Julia Goerges, who backs up her upset of No.5 seed Caroline Wozniacki with a comfortable triumph of American Falconi. Books her place in the fourth round for the first time, where 11th seed Sara Errani awaits.
What a confident game from the Belgian! Dropshot and backhand winners bring up a pair of match points - and she converts on the second. Through to the fourth round where she will face Andrea Mitu. Who would have predicted that match in the last 16 before the tournament?!
Selon @pmouratoglou @jimchardy a su bien servir sur les points importants, restant calme et concentré #RolandGarros http://t.co/vED1w0Cazg

We're in that part of the day where many matches have all finished at once and there's only a few in action. The biggest is on Lenglen, and Van Uytvanck has taken command in her third-rounder over Frenchwoman Mladenovic.

Chardy def. Goffin 6-3 6-4 6-2
Victoire!!! The Frenchman raises his arms in triumph after serving out the match confidently over the No.17 seed. This is Chardy's second trip to the fourth round in Paris - the first coming way back in 2008 - and he takes on No.3 seed Andy Murray next.
