Unbelievable stuff from Victoria Azarenka. Living dangerously but surviving.
*Azarenka 6-2 4-6 6-6 (9-9) Svitolina
Saved. What a point. We keep saying that but it really was.
Azarenka pushes the envelope with a forehand right on to the sideline.
Svitolina gets it back and another - but Azarenka then dispatches an overhead.

Not so fast, says Victoria Azarenka.
Deep approach and a put-away at the net - and we're back level.
We still have Novak Djokovic against Hubert Hurkacz to come tonight!
The roof will be closed on Centre Court following that captivating battle between Iga Swiatek and Belinda Bencic.
Nobody can take their eyes off Court One for the time being, though...

That was the best passing shot Elina Svitolina has hit all match long, and on the biggest point of the match.

Box office stuff.

A thrilling finish to what's been a fantastic encounter!

Elina Svitolina will not go away, though.

Svitolina does her best Kylie impression - spinning around.
But it's not party time when she twirls on the baseline.
She's fuming at herself for a poor return into the net.
Azarenka clenches her first and calmly grabs her towel.
Swiatek 6-7 (4-7) 7-6 (7-2) 6-3 Bencic
Image source, Getty ImagesTime to hear from Iga Swiatek, talking to BBC Sport's Annabel Croft:
"It wasn't easy. She had match points and I don't know I even came back from match point down in my career. I feel I needed the win to believe in myself in this surface.
"I had my chances in the first set, it wasn't easy to get past that. I wanted to be solid and I'm happy I was really disciplined."
Talk us through emotions facing match points:
"At a point like that you feel you gave your best, but you are still match points down. You are playing a bit easier. She's leading anyway so you have nothing to lose. You're already in a pretty bad position, so I just wanted to play and I guess it worked."
Is she learning to love the grass?:
"I think so. My love is getting bigger and hopefully I am going to have as many days as possible on this surface. This is my best year on grass and the hard work is paying off."
Swiatek 6-7 (4-7) 7-6 (7-2) 6-3 Bencic
Iga Swiatek, having barely caught her breath, is giving her verdict on that stunning comeback victory. We'll bring you that interview shortly.
That really could be the spark which ignites her title push. She had to reach a different level to turn that around.
The four-time major winner is through to the Wimbledon quarter-finals for the first time ever.
Azarenka 6-2 4-6 6-6 (7-5) Svitolina*
Elina Svitolina is disconsolate as an Azarenka mis-hit lands on the baseline and a couple of shots later the Ukrainian slices into the net.
A lovely drop volley, however, keeps Svitolina in touch at the second tie-break changeover.

I am nervous and I don't care who wins this match! They are both champions going at it but I'm feeling the nerves. I can't imagine what they're feeling.

Azarenka is tough as teak. Nerveless returning from the Belarusian puts her ahead in this first-to-10 breaker.
The atmosphere has been slightly dampened.
Although one bloke does shout 'Come on Vicky'.
That's presumably at Azarenka, who I don't think has ever been called Vicky.
