What's going on with Katie Boulter? You'd have expected her to carry on the momentum from her fightback in the first set but here she is a double break down and having to do it all again.
The crowd did their best to pick her up mid-game after a double fault was followed by a shot that went long, but there were groans after more costly mistakes.
Time to dig deep.
Alcaraz 6-1 6-4 6-4 Tarvet
Defending champion Carlos Alcaraz progresses to the third round as Ollie Tarvet bows out.
But what a performance from the Brit on his Centre Court debut.
He gave as good as he got for large portions of that match.
The pair embrace at the net, with Alcaraz wrapping his arm around Tarvet and congratulating him on his display.
The Spaniard's hunt for a third Wimbledon title is still alive.

Double faults were an issue for Katie Boulter for a brief time during her first-round win over Paula Badosa.
The British number managed to pull herself out of it in that match but it's been a fairly consistent problem today - it's 10 double faults now for Boulter.
It allows Solana Sierra to bring up another couple of break points. The first is saved but Boulter puts the ball into the net on the second.
Seems likely that it'll go to a deciding set for Boulter again.
*Alcaraz 6-1 6-4 5-4 Tarvet
Ollie Tarvet wasn't going to hand this on a plate to Carlos Alcaraz, was he?
He holds, forcing the Spaniard to serve for the match.
*Boulter 7-6 (9-7) 1-3 Sierra
Break consolidated for Solana Sierra with a lovely, delicate drop shot to secure the hold.
Again, there was a small window of opportunity for Katie Boulter at 15-30 but a couple of loose backhands let Sierra off the hook.

The body language and focus of Oliver Tarvet doesn't appear to have dipped at all. You often see players go a little flat after they've lost a set, he hasn't been like that.

There's a lot of people on their feet cheering Oliver Tarvet for just the effort as well to not let himself go down. He will absolutely try his hardest to the last point of this match.

Burrage/Kartal 4-6 4-1 Bouzas Maneiro*/Cavalle-Reimers
Jodie Burrage and Sonay Kartal move closer to taking the second set.
An ace from Burrage is followed by a clever shot which she just scoops over the net with Jessica Bouzas Maneiro unable to return it despite her very best effort.
The British pair has improved greatly from their performance in the first set.
Alcaraz 6-1 6-4 5-3 Tarvet*
It's a routine hold for Carlos Alcaraz, who puts himself within a game of the third round.

Katie Boulter is going to have to do it the hard way again.
Just one break point for Solana Sierra in this game and that's all she needs, walking at a second serve from Boulter and firing it down the line for a winner.
The Argentine will have new balls to serve with after the changeover.
*Alcaraz 6-1 6-4 4-3 Tarvet
And just like that, Carlos Alcaraz restores his break lead.
The pendulum swings back the Spaniard's way.
Burrage/Kartal 4-6 3-0 Bouzas Maneiro/Cavalle-Reimers*

Jessica Bouzas Maneiro and Yvonne Cavalle-Reimers look stunned by what has unfolded on court four.

Boulter 7-6 (9-7) 1-0 Sierra*

Boulter manages to save it, gets to advantage herself... only to double-fault again - that's nine in the match now.
It doesn't cost her this time with a big serve out wide eventually securing the hold.
*Alcaraz 6-1 6-4 3-2 Tarvet
Ah, it's such fine margins.
After the net comes to Carlos Alcaraz's aid at 40-30, the Spaniard hits a stunning forehand cross-court winner that finds the tramlines to break.

*Boulter 7-6 (9-7) 0-0 Sierra
Gary Rose
BBC Sport at Wimbledon
Few things cause a bigger groan here than someone in the crowd failing to catch a tennis ball, as just happened now. That's quite a lot of pressure for the potential catcher to shoulder.
Speaking of pressure, that's what Solana Sierra has been putting Katie Boulter under, but the Brit deals with it well to take the first set. It was nowhere near as comfortable as she would have liked but she got the job done, prompting huge cheers from the crowd.
