It was a big serve from Gauff and you wonder whether Vesnina is starting to get a better read and timing on her return.

Now she needs a good service game of her own.

A fist pump from Elena Vesnina after she thumps a winner beyond Coco Gauff.

It brings up break point and a chance to get on the board in this second set... and the Russian gets it when Gauff winds up a forehand but hooks it into the tape! That's the first time the teenager has been broken at this year's Wimbledon.

The umpire calls time and Elena Vesnina returns to her feet, wiping her forehead with a towel en route to the baseline to receive the Coco Gauff serve.

Gauff rattles down a couple of racquet-rumbling efforts before Vesnina gets strings on a slower second serve and the American then prods long. Deuce.

Daniil Medvedev means business on Court One.

The second seed breaks in the opening game of the third set, before serving his way to a 2-0 lead against Carlos Alcaraz.

Croat Marin Cilic is a potential third-round opponent.

So a medical timeout for Elena Vesnina, and it looks like she is getting some treatment on her back.

Coco Gauff sits patiently, pure focus, taking on some water.

Elena Vesnina has the trainer on and is receiving some treatment on the ground besides her chair.

This is a match worthy of a Wimbledon final, let alone a second round match on court two.

Just a little loose from Elena Vesnina and this match could be getting away from her. Coco Gauff brings up two points for a double break but can't reach a superb Vesnina backhand on the first.

Gauff challenges, but that just nibbled the baseline chalk! One to go, and this time the American takes it after an enduring exchange with a delightful forehand that only just clears the tape.

You have to feel it's a long way back for Vesnina now.

We've been seeing those rallies time and time again. An hour and 49 minutes into this match and they are still producing them. Over 20 shots!

Coco Gauff just needed the one break of serve to take the opening set and confidently backs up her break at the start of the second to hold and maintain her advantage.

It comes after one of the points of the match so far! Gauff manages to anticipate an Elena Vesnina smash and keeps it in play, before lobbing the Russian at the net, but the American then stands a drop shot up and Vesnina puts it away.

Despite the best efforts of young Alcaraz, Medvedev takes a big step towards the third round as he seals the second set 6-1 on serve.

He hasn't dropped a point on his first serve yet.

Daniil Medvedev's quality and experience is beginning to shine through on Court One.

The Russian has really found his rhythm now and will now serve for the second set following a third break of serve against youngster Carlos Alcaraz.

Still, it's been some showing from the teenager so far. A real talent.

The Russian saves the first with a serve that skips up at Coco Gauff but the American is all over the next, she engineers and awkward return for Elena Vesnina and the 34-year-old wraps a backhand into the tape. Gauff breaks in the opening game of the second set.

Huge chance for Coco Gauff at the beginning of the second set as Elena Vesnina throws down a double fault to hand the American three break points...

Another special rally and this time it goes the way of Sorribes Tormo. Getting the crowd going - she deserves every bit of the applause.

Coco has had so much fanfare, she's played on such big stages, come through big matches, she's such an incredible competitor.

She trusts herself in big moments, she trusts her game.

And Coco Gauff gets it!

The American stings down one of those trademark serves and Elena Vesnina can't pick it up over the tape. The teenager takes the opening set in 32 minutes.

Carlos Alcaraz is once again unable to consolidate his break, as world number two Daniil Medvedev responds by taking his fourth break point opportunity to lead 3-1.

Some huge serving by the Russian take him to 40-15, and Alcaraz is able to land a volley before a delightful sliced backhand at the net from Medvedev seals the hold.

The crowd are on the side of the Spanish teenager, however they can't help but applaud that from Medvedev.

Lovely width on a looping forehand from Coco Gauff, but the American follows up with a double fault.

There's some serious zip in the next serve and Elena Vesnina can only prod it long in response. The Russian is all over a slower second serve on the next however, scuttling to the net as Gauff pops a lob long. But then comes a massive first serve once more... set point.

Not a happy day for one of tennis's golden couples, Gael Monfils and his fiance Elina Svitolina.

The women's third seed was shocked by Magda Linette earlier on Thursday.

And her beau is also out, 13th seed Monfils losing in four sets in the second round to unseeded Spaniard Pedro Martinez 6-3 6-4 4-6 7-6 (7-5).
