Alcaraz was maybe not thinking he would have to go to his best tennis so quickly in this match but this is new territory for Lajal – he is not used to playing best of five sets.

Veteran Swiss player Stan Wawrinka saw off the challenge of Great Britain's Charles Broom in round one at Wimbledon.

Here's how he wrapped up victory...

It's been a pretty entertaining match, I'm enjoying what I'm seeing here.

I think Carlos Alcaraz will be relatively happy with his performance so far and he'd love to get a straight-sets victory here.

As tradition dictates, defending women's champion Marketa Vondrousova will open play on Centre Court tomorrow.

The Czech sixth seed takes on Spain's Jessica Bouzas Maneiro before seven-time men's champion Novak Djokovic faces Czech qualifier Vit Kopriva.

Djokovic, who is looking to match Roger Federer's record of eight men's titles, will plays for the first time since have knee surgery just 25 days ago.

Over on Court One, 2022 ladies' champion Elena Rybakina, French Open finalist Alexander Zverev and women's top seed Iga Swiatek start their campaigns.

British men's number one Jack Draper plays about 16:00 BST on Court Two, with female counterpart Katie Boulter in action about 14:00 BST on Court Three.

The pair, who are both seeded for the first time, are among 12 Britons playing on day two.

Arthur Fery is flying now.

The Brit breaks Daniel Altmaier in the second game of the third set and then goes on to hold to love.

A three-game lead... surely no looking back from here?

Mark Lajal has decided to go for a bathroom break after losing that second set.

He's come so close and pushed Carlos Alcaraz hard, but you always feel like the Spaniard can step it up another level if he needs to.

If Mark Lajal is going to cause a huge opening shock, then he's going to have to fight back from two sets down against the reigning champion.

Carlos Alcaraz took the opening set on a tie-break and the crucial moment in set two came with a break in game 11.

Mark Lajal has done superbly, but finds himself with a mountain to climb.

Job done for Jasmine Paolini.

The Italian seventh seed watches a forehand from Sara Sorribes Tormo fly just wide and she makes it through to round two.

The last three points from Carlos Alcaraz were unbelievable.

But maybe he needs to take a bit more time to compose himself to make that first serve and make the right decision.

Arthur Fery puts that loss of set firmly behind him as he battles hard to hold in the third set.

The 21-year-old, who will celebrate his 22nd birthday next week, is ranked 247 in the world but is more than holding his own against the number 80 ranked Daniel Altmaier.

Three set points for Alcaraz.

Both of them rattling through their service games and struggling to neutralise.

Nice to see how much these two are enjoying it. They look like youngsters out there loving the sport.

From 40-0 up Mark Lajal loses his serve and it is at a crucial point.

Carlos Alcaraz will now be serving to gain a two-set advantage.

Deuce on the Mark Lajal serve, with Carlos Alcaraz flicking away a winner at the net. Both David Beckham and David Attenborough, up in the Royal Box, like what they're seeing.

Alcaraz will be serving for the set if he can win the next two points.

There's a little giggle around Centre Court as someone screams at the top of their lungs "Come on Mark" just before the Estonian steps up to serve.

A Carlos Alcaraz supporter doesn't give it the same amount of welly when he yells "Come on Carlitos".

Four-time major winner Naomi Osaka returns to Wimbledon today for her first match here in five years.

The 26-year-old Japanese missed the 2023 tournament because she was pregnant with her first child, Shai, who was born in July last year.

In 2022, Osaka was injured while in 2021 she took several breaks from the sport to protect her mental health.

Osaka, ranked 113, has been given a wildcard and says she is "very starry-eyed" about returning to Wimbledon, where she has never gone beyond the third round in three previous appearances.

At the recent French Open, she had match point against eventual champion Iga Swiatek in the second round but eventually lost 7-6 (7-1) 1-6 7-5.

She opens against French world number 53 Diane Parry, on court two shortly.

• Daniil Medvedev, Casper Ruud, Grigor Dimitrov and Maria Sakkari among the first-round winners on day one
• Great Britain's Heather Watson and Charles Broom lose in straight sets - five more British players scheduled to be in action on Monday
• World number three Aryna Sabalenka pulls out of Wimbledon because of a shoulder injury

Still to come: Emma Raducanu, Coco Gauff, Jannik Sinner and plenty more...

It's nail-biting stuff as Daniel Altmaier and Arthur Fery go back-and-forth in the tie-break.

Fery has a chance at set point after Altmaier's usually reliable backhand fires wide but the Brit can't take advantage as he goes long.

And it's a huge chance missed as Altmaier earns his own chance at set point and makes it count.

We've got a real match on our hands here.
