Radwanska 3-6 7-5 7-8 Cibulkova*
Yep, we're still going on court three.
Neither Agnieszka nor Cibulkova fancy holding serve. They just keep breaking each other back and forth.
Slovakia's Cibulkova is now serving for the match. Let's see if she can see it out before we hit the three-hour mark.
Halep 6-7 (5-7) 6-4 Keys
We are going long on court two.
Fifth seed Simona Halep nicks the final game of the second set against serve to drag American Madison Keys into a decider.
Anyone's call from here.

Frankly it would be more newsworthy if she wasn't. I think she just sleeps in a Royal Box broom cupboard for the fortnight, consuming only tennis and Pimms.
Querrey 6-4 7-6 (7-5) Mahut
Jonathan Jurejko
BBC Sport at Wimbledon
We've got a teeth-grating arm wrestle between Sam Querrey and Nicolas Mahut. Neither man is giving much away on their serve, Querrey having the few opportunities that are coughed up.
The American 28th seed snaffles the mini-break in the tie-breaker, taking the second set with the tenderest of touches at the net.
Querrey's not quite reaching the same levels as he did against Djokovic - shock, horror - but he is doing more than enough. He's one set away from a first Slam quarter-final.

It's Yaroslava Shvedova against Lucie Safarova on court 12 (a commentator's nightmare with those names).
As it stands, Shvedova of Kazakhstan is going through to the quarter-finals.
She's 6-2 4-3 up against the 2014 semi-finalist. Watch this match here.

Rosh: Hope all those questioning equal prize money for women tennis players are watching Radwanska v Cibulkova...

Sam Querrey showed remarkable finesse to perfectly place this forehand winner down the line against Nicolas Mahut.
Novak Djokovic's conqueror is two sets up against the Frenchman.
Inch-perfect winner from Querrey
*Federer 6-2 6-3 3-4 Johnson
Steve Johnson plays a bit of golf and obviously knows how to replace a divot.

Steve Johnson takes a tumble on Centre Court as the green carpet slips out from under him.
The American mimes replacing a divot to giggles.
These two break points for Federer are less of a laughing matter though. Time to knuckle down. And Johnson does, knocking back the great man once more.

We have a break on court three...and it's gone to Dominika Cibulkova.
The Slovak will now serve for the match. Two hours and 45 minutes gone!

Former world number one on BBC TV
That was a little self inflicted with the lack of first serves from Johnson.
He was wondering if that last return was going to go out and he had a swing at it.

Breaks don't count if you can't back em up.
Roger Federer brings the third set back on serve.

What a battle on court three right now. Dominika Cibulkova and Agnieszka Radwanska are going toe-to-toe in their fourth-round match.
Cibulkova was serving for the match in the second set but third seed Radwanska broke back and has just wasted a match point herself.
They're now 6-6 in the deciding set. Watch all the drama here.
Federer 6-2 6-3 1-3 Johnson
Return to your seats. Fed-Air has run into a little turbulance.
Steve Johnson steals a break in the third set. Can he drag out this encounter and ask some questions of the Swiss great?
Johnson is coming into Wimbledon on the back of a win at the Nottingham Open and is trying to reach a Grand Slam quarter-final for the first time.
Image source, Getty ImagesJames Stevenson: Tremendous match on court 3. Cibulkova the dominant force but Radwanska's defence has been stunning!
Kelly Cooke: What a joy it is to watch @rogerfederer, external play. We don't know how lucky we are to witness him play
Charlotte Hodgson: Spotting the guy dressed as a strawberry on centre court is making this match so much more entertaining!
Halep 6-7 3-3 Keys
BBC World Service
Fifth seed Simona Halep, who is currently playing Madison Keys in the fourth round of Wimbledon, has said it is "50-50" whether she will compete at the Rio Olympics because of fears over the Zika virus.
She earlier told BBC World Service: "I think a lot about this, it's not easy to take the decision, I said after this tournament I make the decision whether to play or not, but I'm very worried about Zika virus and it's tough to say something, it's 50/50 I'm planning to go, but it's very dangerous and very scary for me.
"I spoke already with my doctors at home, with many doctors actually and I'm not sure yet, but sure I will research about this thing and I will make a decision. My health is more important than tennis."
