This goes down to Swiatek digging down so deep. She was not playing her best tennis, but she found a way.

The mark of a champion out here on Centre Court. She takes the applause of the crowd and Swiatek is into her first Wimbledon quarter-final.

Iga Swiatek survives the toughest of tests.
What a way to reach your first Wimbledon quarter-final.

The collective gasps I've just heard watching that final point!
Iga Swiatek seizes her first match point with a brave and brilliant cross-court forehand which scorches the line.
The top seed has done it!
Match of the tournament? I'd say so, but I've not been able to follow the other match on Court One closely enough to confidently say...
What a night.
Azarenka 6-2 4-6 6-6 (2-2) Svitolina*
The mini-break did not last long.
In fact, Victoria Azarenka turns it around, winning both points on the Svitolina serve, the latter with a luscious backhand winner down the line.

Fans are jumping to their feet every time Svitolina wins a point.
Azarenka 6-2 4-6 6-6 (1-2) Svitolina*
Azarenka sends a forehand long and Elina Svitolina is up a mini-break.
But a long way to go, of course.

The chap next to me turned to me earlier and asked who I thought would win. I said I thought Swiatek would get it done and he just turned to me and said ‘now, now is the time’.
How very profound. As it happens he could be right as Swiatek comes back from 0-30 to set up match point.
*Swiatek 6-7 (4-7) 7-6 (7-2) 5-3 Bencic
Oh no!
Dramaaa.
Bencic had already used her last challenge. If she had challenged that call, she would have two break points right now.
Instead, Swiatek moves to match point.
Azarenka 6-2 4-6 6-6 Svitolina*
Elina Svitolina goes too big on two forehands from 30-30 and it's a champions' tie-break to decide who goes through to the quarter-finals.
First to 10 remember.
*Swiatek 6-7 (4-7) 7-6 (7-2) 5-3 Bencic
Wow!
A double fault.
Belinda Bencic has 0-30.
Azarenka 6-2 4-6 5-6 Svitolina*
Victoria Azarenka has a lot of court to place her forehand - but puts it inches wide. 30-30.
Elina Svitolina two points from the quarter-finals.
*Swiatek 6-7 (4-7) 7-6 (7-2) 5-3 Bencic
Belinda Bencic does what is required.
A hold of serve forces Iga Swiatek to serve for the match.
Anyone else really wanting this to go to another tie-break?
Swiatek 6-7 (4-7) 7-6 (7-2) 5-2 Bencic*
It's just a shame these two matches are on at the same time!
Blockbuster stuff on both courts.

This is breath-taking stuff from Azarenka and Svitolina, it really is.
And it is not just the players who are gasping.
The Court One crowd is agog at the intensity of these rallies.
Ferocious stuff from both players.

It has gone gloomy overhead and I am sure Bencic is feeling a little gloomy when she thinks back to those match points she had in the second set. It is hard to believe how quickly it has gone away from her, but that is tennis, it happens so often.

‘Come on Iga!’ are the cries around Centre Court, now.
It’s certainly looking like those fans will get their wish.
Swiatek 6-7 (4-7) 7-6 (7-2) 5-2 Bencic*
Neatly done by Belinda Bencic, dragging Iga Swiatek around the court before tapping a volley over for 15-0 in this must-win game.
*Azarenka 6-2 4-6 5-6 Svitolina
This is some jaw-dropping tennis. Both players absolutely giving it their all.
The balls are getting an absolute leathering on Court One.
Two more holds of serve - Victoria Azarenka must pull out another to remain in the tournament and force a champions' tie-break.
