That's good to see. A big smile appears on the face of Pedro Martinez as the crowd celebrate his first game, somewhat more enthusiastically than he perhaps expected.

Most may have already decided the outcome of this match, but that tweener is further evidence that he's beginning to enjoy himself a little bit more on the big stage.

Things are going rather swimmingly for 22nd seed Flavio Cobolli out on court 12.

The Italian won the first set 6-2 and is now a break up on 15th seed Jakub Mensik in the second.

It is the first time both these players have met another seed at Wimbledon so far this year and it is currently Cobolli coming out on top.

You have got to make the Italian think about his forehand because his backhand is not going anywhere.

It was tactical for Martinez to take a medical time out because he has disrupted the rhythm. But Sinner knows he will win this match so he just needs to keep his concentration.

Elena Rybakina has to save a further two break points deep in the opening set but comes through with a simple finish at the net.

The 11th seed is no guaranteed at least a tie-break and puts the pressure on 23rd seed Clara Tauson.

Hello!

Is this the most elaborate hustle of all-time?

Pedro Martinez holds to love, looking like a new man after that medical time out!

Right, let's see if the magic sponge* has done the trick for Pedro Martinez after that medical time out.

He'll serve to stay in this first set.

*There was no magic sponge.

Well that didn't last long... Mirra Andreeva breaks again, this time to love!

Hailey Baptiste just can't get her forehand swinging this afternoon.

Mirra Andreeva is the hottest teenage prospect in the sport - no question.

She has already won two WTA 1000 titles - the highest tier of tournament below the Grand Slams - this year in Dubai and Indian Wells.

However, we still sometimes see her youthful exuberance and inexperience on the biggest stages.

The little dip to lose serve there is another sign.

You have got to put your neck out and go for it. Martinez may get a little bit longer than an hour and a half but not much. Sinner looks like a man on a mission.

It can get a little bit embarrassing on Centre Court if you don't get a game on the board.

Here comes the trainer, that makes sense for Pedro Martinez.

I would have taken the pain meds about half an hour before.

This is sad because here is a guy who will probably never be on Centre Court again, huge moment for him.

Defining moment in his career to get to the third round of Wimbledon and play Jannik Sinner.

It is a packed court two with action back under way outside and the fans here have been treat to a tense but thrilling start as a lengthy game ends with Claura Tauson holding.

The clouds above continue to look very moody, but they can be as moody as they like so long as it doesn't rain again.

Liudmila Samsonova and Daria Kasatkina are trading breaks in the second set.

16th seed Kasakina, who lost the opening set 6-2, was trailing 3-1 in the second has just broken back for a second time to get the set back on serve at 3-2.

On court two, Clara Tauson has saved two set points to level at 5-5 against 11th seed Elena Rybakina.

Standing out on Centre Court while you’re getting completely outplayed in every department and watching game after game go against you must feel a very lonely place to find yourself.

Pedro Martinez has no answer here to Jannik Sinner’s near-faultless start.

The world number one is drawing ‘oohs’ and ‘aahs’ from the crowd, who are still able to appreciate this clinical display despite a lack of a competitive edge to this one - so far anyway.

Hailey Baptiste strikes back!

The American has broken serve for the first time in this match, after two rare double faults from Mirra Andreeva.

This time Baptiste gets a bit of luck from the net tape, and she seals the break with a wonder cross-court backhand which the Russian fails to return at full stretch.

Pedro Martinez has called the trainer.

The Spaniard looks to be struggling with his right arm and/or shoulder.

He's got some strapping on the back of his right shoulder, which would explain the rather meek serving so far this set.

It's another Jannik Sinner hold and it's a straightforward one for the Italian.

He's been under such little pressure so far that he relaxes, hitting a couple of loose forehands to give Pedro Martinez 30.

But a sumptuous forehand gives the Italian the hold.

British pair Marcus Willis and Alicia Barnett are facing Mexican Santiago Gonzalez and Slovak Tereza Mihalikova in mixed doubles on court 15.

Barnett was 40-15 up on her service game but misses the chance to force a tie-break and Gonzalez and Mihalikova take the opening set 7-5.

The long forehands just keep coming for Hailey Baptiste - she just can't stop them.

Mirra Andreeva gets an all-important service break to love in this second set, albeit with a little help from the net tape on the winning point!

An absolutely body blow for the American, who needs to change something here to give herself a chance of staying in this third round match.

Eek, this is an uncomfortable watch.

Pedro Martinez is serving at around 95mph right now. It's not clear whether that's down to nerves or if the Spaniard has an issue.

Either way, Jannik Sinner moves a double break up and he does so without barely breaking a sweat.

It has been a tough afternoon for Hailey Baptiste so far and the Court One crowd are doing their best to rally her.

Many fans inside an almost-full stadium are encouraging the American.

Nobody wants to see a one-sided mauling, do they?

Well, apart from Andreeva's team...
