Brilliant retrieving from Hubert Hurkacz, somehow flicking his strings at a ball that looked to be beyond him and making it too tricky for Roger Federer to pick up at the net.

It doesn't faze the Swiss, who edges to 40-15 before undercooking a forehand of his own and then holding with a zipped serve.

Felix Auger-Aliassime holds to love to end Matteo Berrettini's run of five games on the bounce and make the Italian serve out the first set.

Despite Auger-Aliassime delighting the crowd with a tweener on the run, Berrettini executes a couple of volleys to set up three set points.

The young Canadian fights back to deuce, but fails to take two break points. He'll have a third opportunity now...

You think Hurkacz is just going to torch the ball at every oportunity, but that's just not his style.

He's awkard to play against.

Sublime one-handed catch from a fan on the front row as a ball bounces off Federer's racquet and into the crowd.

He holds it up to milk the applause. He's chuffed with that one.

Oooh. That was loose from Hubert Hurkacz, skewing a forehand well wide. He recovers by lashing a serve down the T, followed by an ace out wide. Roger Federer gets some good depth on his next return to force the 24-year-old off course but that wicked first serve strikes again to get Hurkacz over the line.

Right on the corner of the service box, couldn't have been more perfect if Roger Federer tried. He scuttles in to meet a short ball on the next and sweeps it down the line before holding to love with a well-worked serve and volley.

That is some serious power from Berrettini in the previous game. Twice there his forehand return seemed to knock Auger-Aliassime off his feet.

The young Canadian seems to have most of the support from this Court One crowd though.

Britons Arthur Fery and Tara Moore have lost the first set of their third-round doubles match on a tie-break to compatriot Neal Skupski and American partner Desirae Krawczyk.

Liverpudlian Skupski and Krawczyk, seeded sixth, squandered three set points in the tie-break before teenager Fery's return to a Krawczyk serve went straight into the net.

Hurkacz is able to generate some serious whip and bounce on that serve, it almost leaps up beyond Federer's grasp. He rattles to a quick hold and levels up in the second.

It's happened. It's actually happened. The sun has come out at Wimbledon 2021. Well, been and gone.

The mood had changed a bit when Federer went a break up in this second set, a bit more positive, but it's now disappeared a touch now Hurkacz has broken back. The shouts of encouragement return.

What an interesting hour. Federer has pushed up the gears a couple of times but the defensive skills of Hurkacz has got him thinking.

The big-serving Berrettini has settled in quickly on Court One and is within touching distance of the opening set.

Another near-faultless service game takes him to 5-1 and Auger-Aliassime will have to serve to stay in the set after 20 minutes.

Big, out-swinging serve from the eight-time champion to fend off the first, but Hubert Hurkacz delivers a smart, deep return on the next and Roger Federer can only prod it into the net.

The Polish player breaks back. Back on serve in the second.

Well, little bit of trouble once more for Roger Federer at 0-30... and even more trouble when he wraps a forehand into the tape and finds himself three break points down.

It's the perfect start for Matteo Berrettini!

The seventh seed calmly backs up his break on serve to take control of the opening set.

The Italian then lands a delightful backhand winner and leads 0-30 on Auger-Aliassime's next game as the Canadian misses.

With the set threatening to get away from him, the 20-year-old delivers a big forehand to get himself on the board - but a double fault allows Berrettini two more break point opportunities.

And that could be that, as Auger-Aliassime nets. 4-1.

Here's how Hubert Hurkacz surprised Roger Federer to take the opening set...

It's a proper tussle on Centre Court. Hubert Hurkacz edges to another hold but he needs a break to level up in this set...

A fist pump from the Polish player after he picks of Roger Federer with a pacy winner from deep. Roger Federer has a word with the umpire, sweeps his hair to one side and then rifles down a big serve and follows it up with a sweeping forehand winner to hold.

Berrettini is already a star of the game. He's a big guy, huge first serve, huge forehand.

Areas to improve - the backhand can be vulnerable and whether he can finish points at the net.

Sometimes you get a breakthrough and it might be a flash in the pan, but very impressed with him winning in Queens on his debut and here.

Hubert Hurkacz gets out of that one with a couple of snappy serves and he's on the board in the second set.
