Women's number one seed Iga Swiatek beats Jana Fett 6-0 6-3
Gauff 2-6 6-3 1-1 Ruse*
Right then, into the decider we go and it's an impressive hold from Ruse.
But Gauff produces a couple of massive serves, including the match's first ace, on her way to a hold to 30, sealing the game with a delightful drop shot.
This is a really tough one to call.
*Jubb 6-3 1-6 5-7 5-5 Kyrgios
Kyrgios, just as he did in the last set, is looking for a crucial break in the 11th game of the set, 15-30. Jubb on the ropes.
Swiatek 6-0 4-3 Fett*
Swiatek has a furious swipe at fresh air as she charges across to a Fett drop shot and ends up netting.
Bang. Ace. Swiatek holds.
*Jubb 6-3 1-6 5-7 5-5 Kyrgios
The ace total springs up to 20 for Kyrgios, followed by number 21 seconds later as the Australian holds to 15.
*Swiatek 6-0 3-3 Fett
Oh, that's a big miss...
Fett aims down the line and instead hoicks the ball long.
Back on serve we go.
Jubb 6-3 1-6 5-7 5-4 Kyrgios*

A big, big hold from 30-30 for Paul Jubb.
He is a game away from taking us to a decider on court three.
Shouts of 'Come on Paul' erupt around the arena. Over to Mr Nick Kyrgios...
Jubb 6-3 1-6 5-7 5-4 Kyrgios*
A beautiful swinging forehand from Jubb which curls in and kisses the line sees him maintain his serve and it's 5-4. Jubb's only 22 and is going to have a great future in the game.
Can he break the Kyrgios serve now to take us into a fifth and deciding set?
Swiatek 6-0 2-3 Fett*
Into the corner goes Swiatek, and Fett nets, handing Swiatek a break back point.
Swiatek 6-0 2-3 Fett*
Jana Fett still has the break lead in this set.
Iga Swiatek is very quick around the court go, whipping a forehand past Fett at the net to get the first point in the game.
Fett's serve is still a little wild but it clicks enough times to get her to game point, right before Swiatek slams a backhand back at her and she can't return it.
Deuce.
*Jubb 6-3 1-6 5-7 4-4 Kyrgios
Once again Paul Jubb is under pressure on his serve. It's 30-30, if Kyrgios gets the break he'll be then serving for the match.
Swiatek 6-0 2-3 Fett*
Caroline Wozniacki
Former world number one on BBC TV
Fett was winning the games when she was playing aggressively. She needs to try and hold on to that.
*Jubb 6-3 1-6 5-7 4-4 Kyrgios
There's another fine service game from Kyrgios, with a hold to 15 and ending it with ace number 19. Four-four in the fourth set.
Swiatek 6-0 2-3 Fett*
Finally, Iga Swiatek gets herself in front...
...and a miss on the backhand from Jana Fett secures a hard-fought hold for the world number one.
Jubb 6-3 1-6 5-7 4-3 Kyrgios*
Harry Poole

It has been a fourth set dominated by solid holds of serve so far - three of which have seen Nick Kyrgios hold to love.
Though his grievances with the line judges and/or umpire (they seem to be quite general remarks) have continued, the Australian looks fully locked in, for now.
*Swiatek 6-0 1-3 Fett
Super quick feet from Swiatek, darting across to meet a short forehand from Fett, and the qualifier nets.
Gauff 2-6 6-3 Ruse
Gauff backs up that break of serve with a hold to love to put herself in a commanding position to take the second set.
A beautiful drop shot gives her a set point. She can't convert, nor that second one that comes her way as Ruse holds to stay in it with a crunching forehand that sails past Gauff, who loses her footing.
Still, though, Gauff will serve for the second set - and she makes no mistake! That was badly needed.
There's a significant change in Gauff's body language now. Suddenly, the momentum is hers.
*Swiatek 6-0 1-3 Fett
It'll be another chance for Fett though a Swiatek goes long...
*Swiatek 6-0 1-3 Fett
No, that's the wrong shot from Fett, attempting a drop shot and watching it drop to the foot of the net.
Deuce.
Kartal 4-6 6-3 1-6 Pattinama-Kerkhove
British wildcard Sonay Kartal (below), on her Wimbledon debut, has fallen in three sets to Dutchwoman Lesley Pattinama-Kerkhove.
Kartal, 20, was due to play Danka Kovinic, of Montenegro, but she withdrew earlier today with a back injury, allowing Pattinama-Kerkhove in as a lucky loser.
