16:55 - Williams through!
WILLIAMS 6-4, 6-4 COLLINS
Game, set, match Williams! Brilliant turnaround from the number seven seed in that second set. She won six straight games from 4-0 down to secure her place in the second week of Roland Garros. Collins played well!

16:50 - Serena on the brink!
*WILLIAMS 5-4 COLLINS (6-4)
Another break! Williams will now serve for the match after winning five games in a row to come from 4-0 down to 5-4. Incredible stuff from Williams who breaks Collins to love with the help of two double faults.
16:42 - Momentum shift
*WILLIAMS 3-4 COLLINS (6-4)
Another swing! Now Williams breaks, with the 39-year-old getting an extra bit of luck off the net cord on break point, but there is a sense that she is over the dip of the start of the second set.
16:31 - Collins takes charge
WILLIAMS 1-3 COLLINS* (6-4)
Another break! Starting to unravel for Williams who makes another double fault to be broken for the second service game in a row. There were two outstanding winners from Collins in that game.
16:22 - Break back!
WILLIAMS 1-1 COLLINS* (6-4)
Break back! Collins breaks Williams for the first time in the match and that was a sloppy game from the 39-year-old, sealed with a double fault on a third break point. A bit of a dip.
16:17 - Set and a break!
*WILLIAMS 1-0 COLLINS (6-4)
A set and a break! Williams didn't really have to do much to break Collins in the first game of the second set. Too many errors from Collins who changed her racquet on break point. Hmmmm...
16:11 - Williams wins the first set
WILLIAMS 6-4 COLLINS
First set, Serena! Two double faults to start the game from Williams, but she recovers and closes out the first set, 6-4. The seven seed showed her quality in the middle of that set.
15:58 - Serena breaks!
*WILLIAMS 4-3 COLLINS
Break! The first break of serve goes the way of Williams who gives a couple short second serves from Collins the treatment. That's enough to give her the initiative as she breaks.
15:00 - Zverev through!
ZVEREV 6-2, 7-5, 6-2 DJERE
Game, set, match Zverev! A straight sets vistory for Zverev as the German serves it out to love. He secures his place in the fourth around and thre was a big gulf in quality between the two players, in truth.
14:45 - Zverev not far away!
*ZVEREV 4-1 DJERE (6-2, 7-5)
Double break! Long from Djere on break point and Zverev is now just two games away from a place in the fourth round of Roland Garros. A long, long way back for Djere from here.
14:23 - Another break
*ZVEREV 1-0 DJERE (6-2, 7-5)
Break! Zverev gets the break in the first game of the third set and it must be said Djere looks like a beaten man here. The Serbian is struggling to hit through the number six seed at the moment.
14:18 - Second set, Zverev!
ZVEREV 7-5 DJERE (6-2)
Second set, Zverev! Five games in a row from the German to secure the second set. Zverev was poor at the start of the set, and in the middle too, but came strong towards the end.
14:14 - Turnaround!
*ZVEREV 6-5 DJERE (6-2)
Break! Four games in a row for the sixth seed and Zverev is now just a game away from a two sets lead! Djere has made a few too many errors in these last few games.
14:07 - Zverev on serve!
*ZVEREV 4-5 DJERE (6-2)
Wow! Incredible from Zverev! Djere had THREE set points at 40-0, but the Serbian got a little tight all of a sudden, his German opponent dictated a few points and he breaks back!
13:54 - Djere in front again!
ZVEREV 2-4 DJERE* (6-2)
Another break! Djere hits back with another break! Two double faults from Zverev certainly helped him there, but the Serbian is doing a much better job of handling the speed from his opponent.
13:49 - Zverev breaks
*ZVEREV 2-3 DJERE (6-2)
Break back! Djere allows his level to drop somewhat and Zverev takes advantage. A couple of close calls that had the umpire come out his chair to check the mark, but we're back on serve in this second set.
13:37 - Here we go!
ZVEREV 0-2 DJERE* (6-2)
Break! We knew there would be at least one in the match and there's the first Zverev dip! A dreadful game from the German who made one double fault and two unforced errors to be broken to love.
13:30 - Zverev on his way
ZVEREV 6-2 DJERE
First set, Zverev! 10 points in a row on serve and the sixth seed claims the first set in convincing manner. Djene has really struggled on Zverev's serve. Not looking good for him.
13:15 - Rain at Roland Garros!
Play has been suspended on all courts at Roland Garros with the exception of Court Philippe-Chatrier where the roof has been brought over and Zverev and Djere continue to play.
13:09 - Zverev starting well
*ZVEREV 3-0 DJERE
Double break! Zverev is three games to the good in this opening set. That was a bit of a mammoth game (would you expect anything less from Zverev), but the sixth seed ultimately had too much power for Djere.
12:59 - Good start!
*ZVEREV 1-0 DJERE
Break! The perfect start for Zverev who gets the break in the first game of the match. A long game, lots of rallies, but the sixth seed had the beating of Djere and grinds it out. Good signs for him.
11:49 - Pavlyuchenkova through!
PAVLYUCHENKOVA 6-4, 2-6, 6-0 SABALENKA
Game, set, match! The number three seed falls and the way the match ended - with a screwed backhand beyond the baseline - summed up Sabalenka's performance. Too many errors. Too erratic. Pavyuchenkova played a good match and gets her reward - a place in the fourth round!
11:17 - Sabalenka levls up!
PAVLYUCHENKOVA 2-6 SABALENKA (6-4)
It's a one-set shootout! Sabalenka breaks for the second successive time and the number three seed is back on level terms. Only four enforced errors in that set. That was the difference.
10:38 - Pavlyuchenkova one set up!
PAVLYUCHENKOVA 6-4 SABALENKA
First set, Pavlyuchenkova! The Russian lost the first three games as Sabalenka started well, but she did so well to wrestle back control from the number three seed. Sabalenka has work to do!
Day Six of the French will see Serena Williams continue her pursuit of that elusive record 24th Grand Slam title as she faces Danielle Collins in a battle of the Americans.
High-flying Aryna Sabalenka is also in action against Anastasia Pavlyuchenkova in a repeat of the recent Madrid Open semi-final.
