Oh that is excellent from Emma Raducanu.

Ena Shibahara takes the next point but then Raducanu returns with a forehand down the line straight into the corner.

Just as it seems like Shibahara is about to close out an easy service game, Raducanu bounces back with some more winners to take us to 30-30.

The Briton is looking in really good touch at the moment.

Shibahara then hits two forehands wide and all the pressure is released.

Raducanu keeps her break advantage.

"Come on!!!!" Emma Raducanu is up for this and celebrates a backhand winner that Ena Shibahara can't get near.

But she slips up on the next point. 30-30.

Emma Raducanu then hits a forehand long and Ena Shibahara finally gets on the scoreboard in the first set.

A big point on Shibahara's serve at 30-30. The Japanese player comes to the net and places a drop shot which is initially called out by the line judge, but is overruled by the chair umpire.

Raducanu isn't happy, but the decision stands. 40-30.

"Please turn off your phone," says the umpire towards the stands. Raducanu is locked in though, taking the next point with a serve and volley and then sealing an important early hold with an ace.

Ena Shibahara is at a career-high 279th in the world in the singles.

But it's in the doubles where the 26-year-old has so far made her name.

She won her first major title at the 2022 French Open alongside Wesley Koolhof in the mixed.

And she also reached the women's doubles semi-finals at Wimbledon in 2021, and the Australian Open in 2022.

Emma Raducanu had surgery on her right wrist and an ankle in May last year before a further operation followed on her left wrist.

It required her to use a mobility scooter to get around, with her admitting it was difficult to "shut your body down".

"I think it's very easy for me to lose sight of where I was exactly a year ago because it is pretty much a year ago to this day, this month," she said.

"You get so caught up in your own world that you want more and more and more. But a year ago I was on a scooter scooting around and I didn't know - there was an element of doubt.

"To be healthy and to be here, I need to cherish it."

Emma Raducanu has just received a great reception from the crowd in Nottingham. There's almost a full house in to watch on what is a very, very cold day in the East Midlands.

Britain's Emma Raducanu said she was in a "really fit place" yesterday.

The 21-year-old skipped the French Open to focus on her fitness, having not played since losing in the first round of the Madrid Open in April.

"Body-wise, physical-wise, I feel really healthy. I feel really strong," said Raducanu, who played her first WTA match at Nottingham in 2021 before going on to win the US Open later that year.

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.
