Good game from Galan. That is the moment in a match or a set where you start to get score-board pressure. He's really free on that serve.
*Sinner 4-5 Galan

You wouldn't know there were 77 places between them in the world rankings.
*Rublev 7-5 6-3 4-5 Bublik
Alexander Bublik gets through the deuce and if he wins the next game, the 23rd seed will take the third set.
Pressure on Andrey Rublev, who hasn't been broken at all and saved five break points in this match so far.
Rublev 7-5 6-3 4-4 Bublik*
It could've been a costly mistake from Alexander Bublik but he gets away with it.
At 30-30, the 23rd seed double faults for the first time in this third set. Andrey Rublev can't take the chance though on the next point and we're into deuce.
*Sinner 3-4 Galan
Chris Bradnam
BBC Sport commentator at Wimbledon
Galan has not blinked yet. He's improved his year end world ranking for every year, for eight years in a row.
Sinner is in a match.
Rublev 7-5 6-3 4-4 Bublik*
The score might not be going Alexander Bublik's way on Centre Court but he has entertained with a couple of underarm serves to surprise Andrey Rublev....
'Expect the unexpected' - Bublik wins game after underarm serve
Rublev 7-5 6-3 4-4 Bublik*
Andrey Rublev doesn't replicate the drama of his last service game. Normal service is resumed and it's a comfortable hold for the seventh seed.
*Sinner 3-4 Galan
Still on serve on Court One - but both players' service games have been tested.
Earlier, Daniel Elahi Galan saved three break points - and Jannik Sinner has just done the same.
Galan may see that as opportunity missed but it's still been an impressive start from the world number 85.
*Rublev 7-5 6-3 3-4 Bublik
Alexander Bublik doesn't let those missed break point opportunities affect his next service game.
The Kazakh ends the game with an ace again and keeps ahead in this third set.
Rublev 7-5 6-3 3-3 Bublik*
Winner. Ace. Winner. That's how Andrey Rublev saves the three break points against him.
The seventh seed gets to deuce and a forehand error from Alexander Bublik sees the third set level again.
Opportunity missed for Bublik, you feel.
*Rublev 7-5 6-3 2-3 Bublik
Signs of life on Centre Court!
At 0-30, Andrey Rublev and Alexander Bublik play out an entertaining rally which involves a net cord and brings both players into the net.
Bublik plays a delightful forehand slice as he moves forward and Rublev's reply goes just wide, giving Bublik three break points. The crowd are the loudest they've been this match.
*Rublev 7-5 6-3 2-3 Bublik
Very quick hold to love from Alexander Bublik. An ace on game point at 40-0 nudges the Kazakh ahead again in third set.
It feels like the 23rd seed is more in this match than at any point so far.
Searle 7-6 (8-6) 6-3 Prado Angelo
Image source, Getty ImagesThere's a notable British victory in the boys singles competition to bring you.
Henry Searle, from Wolverhampton, has knocked out the top seed Juan Carlos Prado Angelo in straight sets.
The 17-year-old, whose rank of 1583 is far below that of the 808th-ranked Bolivian, reached the quarter-finals at the French Open earlier this year.
He went out in the first round at Wimbledon last year but will be looking for a deep run following that display!
Rublev 7-5 6-3 2-2 Bublik*
This doesn't feel like a Centre Court match at the moment. The crowd are noticeably quiet.
Another Andrey Rublev service game goes without danger.
*Rublev 7-5 6-3 1-2 Bublik
Something for Alexander Bublik to hold on to here maybe...
Two aces from the 23rd seed help him to a love hold.

BBC Radio 5 Live commentator
Rublev is playing extremely well. He is navigating all the various unpredictable challenges that the man from Kazakhstan throws.
Rublev 7-5 6-3 1-1 Bublik*
Alexander Bublik takes Andrey Rublev to deuce but once more, Rublev doesn't give him a break point to look at and holds well.
Impressive stuff from the 25-year-old against a player he lost to in a final two weeks ago.
*Sinner 1-2 Galan
Todd Woodbridge
Former Wimbledon doubles champion on BBC TV
I have watched Darren Cahill's coaching career flourish. Sinner already had a coach and he doesn't bring an ego to the coaching set up. It's not all about forehands and backhands. That's how he gets the results, by understanding the player.
*Sinner 1-2 Galan
Well done, Daniel Elahi Galan.
The unseeded underdog saves three break points against eighth seed Jannik Sinner.
It's been a really entertaining start on Court One, with Galan racing in to not only reach a drop shot, but execute a fantastic lob into the corner to save one of those break points.
That match is on BBC Two or on iPlayer if you want to check it out - remember you can watch the matches on all courts here.
*Rublev 7-5 6-3 0-1 Bublik
Michael Emons
BBC Sport at Wimbledon
Image source, EPAAt 5-2 down in the second set and a set down, Alexander Bublik thought 'why not' and sent in another underarm serve - the second time he had done so this match.
Just as the first time where he clinched the fourth game with it, he did it again to seal game number eight. This time Rublev didn't react as quickly and got there on the ball's second bounce.
Strangely enough, it was game six, the one in the middle, where Bublik was serving normally, and that was the one where he lost his service game, ultimately proving decisive.
The underarm serving gave everyone, apart from Rublev, a chuckle, but Rublev had the last laugh in the set as he took it 6-3 to move one set away from a potential clash with Novak Djokovic (or Hubert Hurkacz) in the quarter-finals.
By the way, the clouds overhead are now looking pretty miserable. The roof is still open but there are some very nervous glances skywards from those in the Centre Court stands.
