Sho Shimabukuro rallies a little, benefitting from two Norrie errors, but the Briton then whacks over a class serve which is returned into the net.

Top seed Cam Norrie does get the early break, seeing Sho Shimabukuro clatter a forehand into the net.

The perfect start for the British number one.

Qualifier Sho Shimabukuro is ranked 215th in the world with a career-high of 135.

This should be an easier tie for Norrie.

This is a first match in Nottingham in six years for Cameron Norrie.

Emma Raducanu speaking after her win: "It's been quite a few weeks since I last played a competitive match so I didn't really know how it would go. I think my intentions were great from the start.

"I think I played a really good match. At the end I think inevitably if you're 6-1 5-1 up something probably could go wrong. I was trying to not let it get to my head and just preparing and fighting for each point. I knew that even though I lost three games in a row I still had a chance to win the match.

"I'm very pleased with how I dealt with the circumstances today.

"It's amazing to be playing on home turf, it's been so long since I last played in the UK. To come here and feel like everyone is really behind me is really nice. I'm cherishing every moment of that too."

That's Emma Raducanu's first appearance on grass in 713 days. Let's hear from her now...

And then Raducanu brings up match point with a cracking return which forces an error. 30-40.
