Britain's Mimi Xu spoke to BBC Radio 5 Live after making her Grand Slam singles debut against Emma Raducanu: "I'm not going to go as far and say it is my dream debut because I didn't win, but I am so honoured I got to play against a Brit on Court One with an amazing crowd. I wouldn't have wanted it any different.

"When I came off court I had tears on my cheeks - but I wasn't upset at all, it was just the emotions coming out at the end. I think I have done myself really proud and enjoyed every single moment out there.

"My level is not far away - it has really ignited a fire within me and I really believe in myself now."

Since those two lengthy games at the start of this set, it's been a succession of quick, fairly straightforward holds.

Katie Boulter gets the latest with an 110mph ace down the middle taking her to 30-15. From there, she makes sure not to give Paula Badosa even the slightest glimmer of a chance.

Now to see if the Brit can find a crucial break...

It is all getting away from Mika Stojsavljevic now.

A smash into the net and a couple of wild forehand volleys gives Ashlyn Krueger two opportunities to serve this match out.

That was a really positive game for Paula Badosa.

She was hitting her serves and her spots. She was going for the next shot much bigger in that game than in the game before.

It isn't a matter of being tired, it is a matter of believing that you can still hit those shots. It is important to not get too cautious.

Strong hold from Paula Badosa.

She brushes off a double faults and takes the game to 30 with a brutal backhand to the corner.

Paula Badosa can't believe it!

She worked her way back into the point but then Katie Boulter comes up with a great defensive shot to force the error.

I think Boulter got away with one there.

An ace out wide and Katie Boulter holds to 15.

The crucial point came at 15-15 with the Brit in control, only to overrun one as she came towards the net and find herself on the back foot as Paula Badosa unleashed a series of huge shots.

But some brilliant defence keeps Boulter in the point, one shot forcing Badosa all the way back and into the corner of the court before the Spaniard slices wide.

Who will blink first on Centre Court?

Is experience beginning to tell?

Mika Stojsavljevic is struggling for the same level of consistency as this match goes on.

Having been a break up, the British wildcard is now a break down to the 31st seed Ashlyn Krueger.

Hopes of a dream run to the second round on her debut in the main draw are beginning to slip away for the teenager.

Fifth seed Taylor Fritz is in a battle with French world number 36 Giovanni Mpetshi Perricard on Court One and the American has dropped the opening set on a tie-break.

There was only one break point for either player before the breaker, which Mpetshi Perricard won 8-6.

Fritz, who won his fourth Eastbourne title at the weekend, has work to do if he's to make round two at Wimbledon.

As quickly as Katie Boulter got herself in front, Paula Badosa levels it up.

Up 40-15, the ninth seed just helps the ball into the corner with Boulter beaten and it stays on serve.

What a noise there was here on Centre Court for that winner at 30-15 by Katie Boulter! People were on the feet after it had looked to have gone away from her.

Paula Badosa battled back to deuce but Boulter dug in to hold.

This is an absorbing encounter. After two widly contrasting sets, this could go either way.

Fantastic from Katie Boulter!

She is at full stretch to reach a searing forehand from Paula Badosa but manages to get it back across the net as the Spaniard advances.

Badosa then gives Boulter a half a chance and the Brit takes with a fine backhand passing winner.

It goes to deuce again but Boulter gets the hold to edge ahead.

Paula Badosa is talking to her camp but I think she needs to give credit to her opponent.

She hit two great balls right on the baseline and Katie Boulter gave them right back. Her shot was just too good - it was one point, take yourself off the hook, Katie just played great and that is okay.

I think Badosa is being a little too hard on herself.

Some of Badosa's lower shots have been extremely impressive - she takes care and discipline with the racquet face. Some of these chopped, blocked shorter returns of serve are quite awkward to play and a lot of players wouldn't be able to handle that.

Badosa really bends her knees, drops her racquet face and brushes up the back of the ball and thunders it into the corner. She has done that a few times and is confident on those types of shots.

If there were concerns that Mika Stojsavljevic could be fall away after losing that tight first set, there shouldn't be.

The 16-year-old has come back out fighting and manages to get a break at the first time of asking in this second set against Ashlyn Krueger.

Can she consolidate it?

Sadly not.

Krueger does not panic and a couple of errors from Stojsavljevic sees her hand the break straight back.

Third time's the charm!

Katie Boulter lets out a shout after earning a third break point but that's nothing to the roar of both player and crowd when Paula Badosa sends a forehand into the net.

Back on serve in this deciding third set.

Two chances going begging for Katie Boulter and it's a really strange shot to miss the second of them.

The Brit comes into and then seems stuck in two minds between playing a drop shot or just slapping a forehand cross court.

In the end it's neither and the ball skews horribly wide.
