Lovely, lovely drop shot from Carlos Alcaraz to secure the hold to start the fourth set.

A fabulously deft touch.

Hmmm.

The double fault rears its ugly head once again. That's a mini-break back for Joao Fonseca.

And Jacob Fearnley fires into the net... it's back on serve.

Lovely tennis at the net from Jacob Fearnley to reclaim control with his second mini-break.

Fearnley in the driving seat.

Ah.

Jacob Fearnley gets too much on his backhand and Joao Fonseca gets a mini-break back.

Carlos Alcaraz lets out a roar as he breaks to win the third set!

Fabio Fognini saves the first set point but then he gifts Alcaraz a second with a double fault.

No saving this one. Alcaraz powers a forehand into the corner and Fognini can only put it into the net, falling to the ground as he does so.

The defending champion is two sets to one up.

Jacob Fearnley lays down an early marker.

Joao Fonseca defended three break points in the opening set and he makes that four here to get to deuce.

A shake of the head from Jacob Fearnley after finding the net to hand over advantage.

And Fonseca gets the job done, despite slipping, when Fearnley forces it into the tramlines.

We go to a tie-break.

Ethan Quinn is able to consolidate the break as the two players sit down for the change of ends.

Quinn is a big serving American, but Henry Searle still managed to put some pressure on in the game and will need to do that again the next time Quinn serves if he is to turn this second set around.

Leylah Fernandez, US Open runner-up in 2021, hits another ace which Hannah Klugman can't reach and pumps her fist in celebration.

However, a double fault gifts Klugman an opportunity as the game goes to deuce.

Klugman hits into the net but a wild swing from Fernandez brings it back to deuce.

Fernandez eventually holds on her service game with yet another ace.

The second round is in sight for the Canadian.

Brilliant from Carlos Alcaraz.

A fantastic drop shot to to bring up break point for the two-time Wimbledon champion.

Jacob Fearnley forces a forehand into wide open space.

Fearnley has the chance to break and take the third set.

Carlos Alcaraz needed that.

Easy service games have been few and far between in this match but the Spaniard gets one to guarantee at least a tie-break in this third set.

You can be sure he'll be doing everything he can in the next game to ensure it doesn't get to that, though.

Yes and no [on electronic line calls]. I think the challenges are always exciting.

The line judges these days get more correct than in my day, but I think it is good having the electronic line calling.

A lot has been said today about Wimbledon's decision to bring in electronic line calling to replace the well-dressed line judges on court.

You can read all about that decision and hear from umpires and former line judges on it here.

But what do you make of it at home? Does the court look emptier? Do you miss line judges?

Let us know your thoughts!

As happened in the first set, Ethan Quinn goes a break up against Henry Searle.

The 19-year-old Brit was able to turn it around last time, can he do the same this time?

Jacob Fearnley gets a massive hold to guarantee at least a tie-break in this third set.

That was exhausting to watch.
