I've said it once and I'll say it again. It's brutal hitting from Iga Swiatek as she leathers a forehand winner to break and claim the first set.
Amazing to think she's never been beyond the quarter-finals here.

*Draper 6-7 (3-7) 3-5 Norrie
That was a much-needed game for Cameron Norrie, just to slow down the Draper charge. A hold for Norrie means he only needs one hold to take a two-set advantage.
Draper 6-7 (3-7) 3-4 Norrie*
And another one. From 4-0 down and a double break behind, Jack Draper is starting to put the pressure back on Cameron Norrie.
The match is swinging in favour of the British number one, although Norrie still has a break in this set.
Swiatek 5-4 Martic*

I tell you what, Petra Martic is not going anywhere in this match!
The world number 85 is playing some tremendous stuff out here and looks as though she's been playing on Centre Court forever.
She ripped a forehand winner down the line that drew a number of 'oooohs' from the crowd.
Ons Jabeur was on a mission earlier today. Here's how she beat American Robin Montgomery:
*Draper 6-7 (3-7) 2-4 Norrie
The Jack Draper fight back is gaining some pace. Two games in a row.
Break point Draper to win back-to-back games after losing the first four of this set.
*Swiatek 4-4 Martic

I've watched a lot of women's tennis in the opening four days of Wimbledon but no one hits the ball quite like Iga Swiatek. It is brutal from the French Open champion.
*Swiatek 4-4 Martic
Petra Martic is good to continue against Iga Swiatek after receiving treatment and play is back under way on Centre Court.
We remain on serve in this first set.
American Ben Shelton and South African Lloyd Harris played out a proper epic today on court 18, with 14th seeded Shelton just edging things.
Here are the best moments from the five-set slog:
Draper 6-7 (3-7) 1-4 Norrie*
Jack Draper gets on the board for 4-1 in the second, but still finds himself a double break down. But every fightback has to start somewhere.

Jack Draper needs to try and mix it up, playing different shots.
I just don't see Draper winning the match if the exchanges stay like this.
Just joining us? Well Britons Cam Norrie and Jack Draper are on Court One.
Norrie is a set up against the British number one, here's how he took the first...

I think we can put the question of whether Cam Norrie's level is still there to bed after what we have all seen in this hour.
This is the tournament where you want to start beating people and rebuild your reputation.
You have to blow him off the court. If you start playing him into a rhythm like Jack Draper has, this is where Norrie is at his best.
*Draper 6-7 (3-7) 0-4 Norrie
Of the last 15 points, Norrie has won 14 of them. When you're hot, you're hot.
*Draper 6-7 (3-7) 0-4 Norrie
A hold to 15 from Norrie and the former world number eight is hitting his top form. Draper looks unable to cope with him at the moment.
Swiatek 4-3 Martic*

Iga Swiatek has put her jumper back on while hitting some serves to keep warm.
We've got a medical timeout here to allow the physio to work on Petra Martic's back. No one wants a bad back!
Swiatek has now run over to have a chat with her team.
Draper 6-7 (3-7) 0-3 Norrie*

Cam Norrie is out for revenge.
He races from one side of the court to the other, staying in the point until he dispatches a brilliant winner down the line.
It looks like he really wants that British number one spot back.
