Zarazua 3-4 Raducanu*
Johanna Konta
Former British number one on BBC TV
Zarazua has been so composed so far. Giving very little away - she seems really comfortable out there.
She hasn’t been in these kind of arenas as often. Raducanu is the heavy weight in that respect.
These players want to be on the biggest stages in your sport, so you’re not just thrown into this unwittingly.
Zarazua 3-4 Raducanu*
Renata Zarazua halts Emma Raducanu's three-game winning streak in style - holding to love.
That was vital, even at this early stage, to stay competitive in this first set and prevent Raducanu rolling over her.
Osaka 6-1 1-6 6-4 Parry
Naomi Osaka, in her first Wimbledon appearance since 2019, is through to the second round for the first time in six years.
A double fault from Diane Parry allowed her to clinch the break and the match, and the Frenchwoman will be heartbroken for the match to end like that.
A cracking watch and we'll hopefully hear from Osaka shortly.
*Zarazua 2-4 Raducanu
Image source, PA MediaRenata Zarazua wins arguably the point of the match so far to move 30-15 as she looks to break back immediately.
The Mexican is backtracking as she loops it over the head of Emma Raducanu - not for the first time - and the Brit can only find the net when returning on the spin.
But Raducanu goes on to see out the game and there's another huge roar.
That hold could prove as big as her earlier break.
Altmaier 4-6 7-6 (8-6) 1-6 6-3 2-0 Fery*

Spirits have dropped on court 16 and if things continue this way, then another Brit will be leaving Wimbledon in the first round as Arthur Fery finds himself a break down in the deciding set.
Altmaier 4-6 7-6 (8-6) 1-6 6-3 2-0 Fery*
It is all looking like a lot of hard work for Arthur Fery on Court 16, so, having been broken in the first game of the fifth set, he will be delighted to be gifted a point by a Daniel Altmaier double fault.
That makes it 30-30 and gives Fery an opening as he tries to break straight back.
However, the door is promptly closed on the Briton by Altmaier, break consolidated and the German is in control.
Zarazua 2-3 Raducanu*
Jonathan Jurejko
BBC Sport at Wimbledon
Coming through to hold for 2-2 boosted Raducanu's belief, allowing her to break in the very next game.
The groundstrokes had some extra oomph - let's forget about the wild overhead - and Zarazua's defence couldn't hold firm this time.
Osaka 6-1 1-6 5-4 Parry*
Another deuce and this time Naomi Osaka holds her nerve.
Diane Parry slips as the ball flies cross court towards her.
Osaka is one game away from her first victory at Wimbledon since 2018.
Zarazua 2-3 Raducanu*
Johanna Konta
Former British number one on BBC TV
Image source, ReutersUltimately I believe Raducanu's biggest asset will be her belief in her own decisions. It cuts out a lot of wasted energy if she has trust in her own decisions.
Because nothing is more crippling than self-doubt.
Zarazua 2-3 Raducanu*
Jonathan Jurejko
BBC Sport at Wimbledon
Phew. Emma Raducanu's relief at coming through that fourth game is mirrored by the crowd's collective exhaling of breath.
Raducanu screamed as she moved 40-30 up, then tapped her temple in the direction of her team after eventually completing the hold.
It's all in the head...
Could that be a turning point in this opening set?
Zarazua 2-3 Raducanu*
Now it's Emma Raducanu's first opportunity to break after Renata Zarazua fails to get under the ball and hooks it into the net.
Raducanu takes it!
It has been so even through the first four games but could this be a momentum shifter?
*Zarazua 2-2 Raducanu
Jonathan Jurejko
BBC Sport at Wimbledon
Here comes the cavalry. The usual influx of fans at the first changeover of the match considerably swells the Centre Court crowd.
It was a long wait. The opening three games took almost 15 minutes as the pair chopped it up in some lengthy rallies.
*Zarazua 2-2 Raducanu
Emma Raducanu saves that break point and takes control with the net cord helping her to advantage.
Raducanu sees it through, surviving a minor scare, to hold and lets out a big scream.
The 21-year-old walks back to the baseline pointing to her temple. She is focused!
Image source, PA MediaOsaka 6-1 1-6 4-4 Parry*
It's remarkably even and the court two crowd are being treated to real jeopardy here.
Diane Parry looked like she was starting to find the upper hand but Naomi Osaka's resilience is keeping this match alive.
Who do you see winning this one?
Altmaier 4-6 7-6 (8-6) 1-6 6-3 0-0 Fery*
Charlotte Coates
BBC Sport at Wimbledon
Arthur Fery has just left the court after finding out he’s going to have to go the distance if he is to book his place in round two.
I saw him clutching at his calf a couple of times in the fourth set, maybe that’s what he was getting treatment on earlier.
*Zarazua 2-1 Raducanu
As you'd expect, the crowd is firmly behind home hope Emma Raducanu but, if you needed reminding, there's a huge amount of appreciation shown when she powers a forehand into the corner at the baseline. 15-15.
Raducanu leads 30-15 and tries the same shot again... this time it goes long - 30-30.
Oh, Raducanu rushes to meet the ball at the net and she gets too much on it as it's volleyed long. Zarazua has break point.
Osaka 6-1 1-6 4-3 Parry*
Alan Jewell
BBC Sport at Wimbledon
Twice Diane Parry has been a break up in the final set but Naomi Osaka has levelled up again after the Frenchwoman fired a forehand into the net.
Many in the court two crowd now applauding and shouting with extra force as they try to help Osaka over the line.
She holds and is now two games away.
Altmaier 4-6 7-6 (8-6) 1-6 6-3 Fery*
After a frustrating couple of games, Daniel Altmaier clinches the set in the most straightforward way: a hold to love.
Arthur Fery had saved another set point in a lengthy service game for the Briton before sending it back over to his German opponent to serve it out.
He couldn't do it the first time but this time he makes no mistake and seals it with an ace down the middle.
Momentum is with Altmaier going into the fifth set...
*Osaka 6-1 1-6 3-3 Parry
Image source, PA MediaWell Naomi Osaka has broken back and we're back on level terms.
Diane Parry's shot just didn't have enough power to make it over the net and Osaka is looking fresher of the two.
This could go either way!
Zarazua 2-1 Raducanu*
Johanna Konta
Former British number one on BBC TV
It has been a bit of time but it’s nice to see Raducanu in good spirits and happy to be here.
Currently it’s not as typical of grass court tennis. There’s a lot of long points.
I imagine Emma will be quite strict in where she wants her mind to wander. She will stay very present, take one match at a time, one point at a time. That will be the lane that she wants to stay in.
