*Sinner 6-2 6-4 1-4 Shelton
Ben Shelton finally gets some joy with the drop shot as a sliding Jannik Sinner doesn't get under the ball and can only scoop into the net. 15-15.
These serves are just getting ridiculous. 138mph from Shelton flies past Sinner and does some damage to the back wall.
Another ace to hold.

Emma and the crowd know that it is important for her to find a way in and stay in touch.
There is always a way back if you can change something up.
Sun 3-1 Raducanu*
Cries of "come on Emma!" as Raducanu finds an opportunity to break back.
A double fault from Lulu Sun hands her the break and that's one overturned. The Brit is up and running on Centre Court.

If there is a problem with Jannik Sinner's wrist he's coping pretty well back on serve as he races to a 40-0 lead.
A brief moment of concern now for Ben Shelton as he loses his footing at the baseline but he's back up quickly and then slots a beautiful forehand cross-court for 40-15.
Sinner goes on to win his first game of the third set.
A huge service game awaits Shelton.
*Sinner 6-2 6-4 0-3 Shelton
We've just seen Jannik Sinner paying extra attention to his left wrist after that loss of game.
Is the Italian carrying an injury?

On the grass courts there is no substitute for match play. In that environment it is completely different and Sun has come through three matches in qualifying and three matches to get to here.
She has almost played a complete tournament to get here.
*Sun 3-0 Raducanu
Fans are piling back on to Centre Court at the change of ends after a refreshment break following Carlos Alcaraz's win.
They're probably wondering what on earth they've come back to.

Ben Shelton glares at his friends while shaking his racquet in celebration. He’s feeling it now.
This Court One crowd is loving this!

Qualifiers are dangerous.
Emma Raducanu knows that from her own experience at the 2021 US Open.
Lulu Sun is proving it again.
She’s full of confidence, whacking clean winners and bouncing around the court.
*Sun 3-0 Raducanu
She's got it at the first opportunity.
Emma Raducanu is already in a spot of trouble here as she sends the forehand wide and Lulu Sun takes the double break at the first chance.

Where has this Ben Shelton been?
The American finds a lovely passing shot down the line to lead 30-0.
Maybe the excitement gets the better of him as a double fault allows Jannik Sinner on the board. 30-15.
But Sinner goes long and Shelton wins his third game in a row.
Sun 2-0 Raducanu*
Goodness me. It's Lulu Sun with all the energy and all the momentum on Centre Court at the moment.
She whizzes the passing forehand past Emma Raducanu to bring up three break points for the double break.

Break point for Ben Shelton and the crowd cheers on the American. We’ve been here for just 74 minutes and already into the third set.
Court One rises as Shelton wins an outrageous rally to break.
Game on?

Lulu Sun likes to base her game around that big serve on first and second serve opportunities.
It is obviously a change for Emma playing a left-hander and the way that she has to try and neutralise will change a little bit today.
Sinner 6-2 6-4 0-2 Shelton*
Ben Shelton was really struggling to get into games when Jannik Sinner was on serve in set one and halfway through set two but he has recently started to find more success.
And now he has a first break point of the encounter.
He takes it!
Shelton's dad and coach Bryan is on his feet.

Let's hope plenty in New Zealand have stayed up to watch this one because their player has got off to a really good start.
Emma Raducanu can't return Lulu Sun's serve and there's the hold to back up that early break.
*Sun 1-0 Raducanu

This contest is going to be shown all over the world - including, thankfully, in New Zealand.
An issue with broadcasting rights meant Wimbledon was initially not shown on television in the Pacific nation.
A late deal saw the matches put on TVNZ+ - a streaming service similar to the BBC iPlayer - but it only had the world feed coverage, which did not show anything outside of Centre Court and Court One.
That meant Kiwi fans could not watch any of Sun's opening three matches on national television.
Today that changes and means, at just gone 4am on Monday in New Zealand, there will be plenty staying up through the night to watch it.
*Sun 1-0 Raducanu
An opening for Emma Raducanu as Lulu Sun double faults for 30-30.
The qualifier serves and follows up with the forehand for game point but tries to do the same on the next point and it ends up long.
Deuce.

Ben Shelton let’s out a huge roar and his friends near me stand to applaud after he holds serve.
The American is trying to get himself going here.
*Sinner 6-2 6-4 0-1 Shelton
Ben Shelton was broken in the first game of the second set but he manages to hold this time.
A huge roar from the American as he comes through a tough game to win to 30.
Small gain for the 21-year-old.
