Katie Boulter is on a roll now and suddenly Harriet Dart's break advantage is under real threat.

Boulter steps up into a second serve, dominates a point and then wins it with a cracking forehand down the line. 15-40.

We're eventually back playing again and Boulter finds some rhythm - pun intended - on her serve.

Two unreturnables and she holds to 30.

The luck just isn't falling for Katie Boulter who is on the receiving end of a net-call to slip to 30-30.

Then some drum and bass starts playing on the loudspeaker.

"Music off please," pleads the umpire. The wrong button is switched and instead the volume rises. The crowd give a polite, if a little confused, laugh.

Harriet Dart is hitting some steamroller first serves. Katie Boulter isn't in this latest game which Dart holds to 15 after Boulter hits a backhand return into the net.

It's early days but Dart looks far more comfortable on the cold centre court.

And the British number two seizes that gift, playing a driving forehand down the line which has Katie Boulter struggling.

Harriet Dart then finishes the point off with an overhead smash at the net. We start with a break.

Well it's a poor start from the reigning champ who slices a forehand into the net to slip to 15-40.

Harriet Dart is gifted two break points.

Strap in folks. Hopefully this will be a good one.

I will warn you that the past two tennis matches I've covered ended in a 03:07 and a 01:40 finish.

So expect this one to go long, I'm thinking world records smashed in a mammoth deciding tie-break.

Harriet Dart has reached the quarter-finals of the past two Nottingham Opens.

She also lost in the last eight at Birmingham last year.

Dart won the coin toss and will receive first.

Last year, Katie Boulter won her first WTA title with a dominant victory in Nottingham over Jodie Burrage in the first all-British tour-level final in 46 years.

The British women's number one ranking was also on the line as Boulter outplayed her good friend 6-3 6-3.

Fast-forward 12 months and Boulter is now ranked 30th in the world. She'll be seeded at Wimbledon.

And we've also had a British victory today in the Stuttgart Open.

Jack Draper, seeded sixth, beat Austria's Sebastian Ofner in straight sets this morning.

He'll face either Andy Murray or Marcos Giron in the second round, with those two taking each other on tomorrow.

This is the second match on Nottingham's centre court after Briton Heather Watson came from behind to beat American Kayla Day 4-6 6-0 6-4 just moments ago.

Watson lost to Katie Boulter in the semi-finals last year.

Her win today was heavily rain-affected. The sun is shining now though, fingers crossed it stays that way!

Andy Murray, who won last year’s tournament, is competing at the Stuttgart Open this week so British hopes lie with the current British number one Cameron Norrie.

Norrie, who has been handed a wildcard, will be hoping to bounce back after his opening round defeat in the French Open earlier this month.

Dan Evans is the other British interest in the men’s section of the draw, but Liam Broady won’t feature in Nottingham after suffering a concussion when he hit his head on a car boot.

In the women’s draw, Emma Raducanu features after opting to skip the French Open to concentrate on the grass-court season. She is joined by fellow Brits Katie Boulter, Harriet Dart, Heather Watson and Fran Jones.
