It's a bit of a tame ending for Del Potro out on court 12 as he wins just one game today, with Pouille racing through the fourth set. The French 32nd seed - who lost to Andy Murray in the Rome semi-finals earlier this year - will play Australian Bernard Tomic in the last 16.
Kuznetsova beats Stephens 6-7 6-2 8-6
"It's great I think it was an amazing match," said Kuznetsova. "I was 5-2 down in the third set but I hung in there. I was really frustrated [about the code violation for coaching] because she warned me in the first set because he talks a lot, and then in the second set he says 'come on keep going' and I get a code violation. It's a big fine and very frustrating."

You have to play the match of your life to beat Serena. We have seen this year a few times that nerves turn up. I don’t know if that is being 34, possibly at the end of her career, chasing the record of Steffi Graf.
These are the types of matches where, maybe at Wimbledon, she'll get her 22nd. She feels so comfortable here on the grass whereas so few players feel at their best. Its an awkward surface to move on. Half of playing here is in your mind.

Serena Williams, speaking to BBC One: "I thought it was a good win. I was really focused and calm. I was at Wimbledon the last time they played on a Sunday. It was nice. I love having Sunday off, but I'm a bit behind on my matches. I've done a third Monday before - hopefully that won't happen this time."

Even when Annika Beck was able to exchange a 20 shot rally with Serena, the champ was too good.
She's now clocked up 300 Grand Slam wins. What a woman.
The man in question is Frenchman Kader Nouni. He's too cool for school.

Russian 13th seed Kuznetsova wins a thriller on Court One, happily watching as Hawk-Eye confirms a Stephens forehand is wide on match point. Kuznetsova was given a warning for coaching earlier in the match but heads off all smiles and chatting with Stephens - it's Serena Williams next for the Russian.

Serena is absolutely flawless. She struck the ball so well - especially in the second set. It was all about Serena. I am sure she will be very happy with her performance and victory. She showed us some brilliance today.

In the blink of an eye, Serena Williams makes it into the last 16 with a simple victory over German Annika Beck.
It only took her 51 minutes. She served it out with an ace.
*Williams 6-3 5-0 Beck
Pint-sized Annika Beck has got the crowd behind her at the moment. And she really needs it, because Serena Williams is trampling all over her.
The six-time champion takes a 5-0 lead and will serve for the match in a jiffy.

Roger Federer speaking to Sue Barker:
"Mentally I am much better. I am more confident than I was coming in a week ago. I know where my mind and game is at. Clearly I now fancy my chances than one week ago.
"Novak was the defending champion and he was the big favourite. Now that pressure switches - maybe Murray, maybe myself. It is an opportunity and that can play tricks on player's minds. You need to focus.
"I like that my kids enjoy the challenging life I have. They like tennis enough to come watch my matches from time to time – they always ask me if they can bring some books out if they get bored!"

Image source, ReutersJuan Martin del Potro and Lucas Pouille are back out on court 12 to resume their rather testy contest from last night - Del Potro apparently told the Frenchman to "shut up" after a disagreement over a line call, just before play was suspended. All appears calm now, with Pouille leading by two sets to one as they get under way again.
Isner 7-6 6-3 6-7 2-6 2-1 Tsonga
When this match-up cropped up, you knew it wasn't going to be a simple one.
Big serving American John Isner, he of the longest match ever fame, and brutish Jo-Wilfried Tsonga have gone to a fifth set in their third round tie on Court Two.

Image source, BBC SportWhile playing tennis on Middle Sunday isn't the norm at the All England Club, it is on Wimbledon Park.
Southfields resident Geoff Smith (the white baseball cap-wearing bloke with the tidy forehand) has brought his net and makeshift court down to the Queue for a sixth successive year.
Not bad a way to pass the time while his partner and their pals patiently wait for Manic Monday tickets.
"There's always a lot of interest from people wanting a game," he says. "I've taken people on from all over the world. It's all good fun."
Be warned if you fancy taking on Geoff. He's a hustler. I didn't even win a point.
