Wow.

I said there were signs that Cameron Norrie had found his rhythm.

But breaking to love? Nobody saw that coming.

The Briton takes the first of his three break points, returning excellently in the corner for Sebastian Korda to send a forehand wide of the baseline.

What an opportunity...

There's no doubt that Victoria Mboko is going to be one of the players to watch in years to come but, as we say with Emma Raducanu, everyone is going to have to be patient and give her time to work it out.

Encouraging signs that Cameron Norrie's found his groove now.

He holds - and with ease - to put Sebastian Korda back on serve.

Victoria Mboko looks to be hitting her stride, but then her service issues cost her once more.

Back-to-back double faults and a shot into the net hand Barbora Krejcikova three break points, and she takes advantage with the second.

Mboko's mentor, former world number three Nathalie Tauziat, gave her plenty of encouragement throughout that first set, but a heavily bandaged wrist appears to be bothering the teenager.

She heads to the locker room at the end of the set.

Sebastian Korda saves a *third* break point with an ace.

He takes the next two points to keep hold.

Cameron Norrie will be kicking himself but those were the first punches he's landed on the American.

Cameron Norrie feeds off free points.

He has started to put a little bit more flight on the ball and he is trying to get the ball up on Sebastian Korda here.

He seems to have made a clear tactical change on court.

Sebastian Korda rattles off *another* ace to save break point.

....another one.

Deary me, what a time to pull out an ace.

Cameron Norrie gets his first break point opportunity of the match...

Great work from Cameron Norrie,

He finds his second ace of the match to save a break point for Sebastian Korda.

He then shows deft hands at the net to execute a beautiful volley, before Korda nets a return.

Watching Sebastian Korda hit a tennis ball is a thing of beauty.

Cameron Norrie has just played a wonderful return and he has clipped it off the baseline for a winner - not many people have that skill.

But there's clearly something that isn't connecting the dots, whether that is physicality or mentality I don't know.

Barbora Krejcikova survives two break points to hold serve, but that's much more like it from Victoria Mboko.

The teenage sensation looks to be growing in confidence - she showed none of her early struggles in holding serve to love.

Sebastian Korda gets his second break point opportunity of the match...

Well, Diane Parry made short work of that.

She wraps up the first set against Petra Kvitova in just 25 minutes.

Kvitova, who will retire after this tournament, got just one game on the board, rallying from a break point down to take the fourth game.

She exited the court after that first-set defeat but is back out now and will be keen to make sure that if this is her last match she puts her best out there.

Cameron Norrie let out an almighty scream when he won the second point of the game to go 15-15.

The Briton presumably thought he could get in Sebastian Korda's head.

But no such luck, as the American continues his smooth serving to put Norrie back on serve.

The pressure's all on Norrie at the moment.

A more straightforward hold for Cameron Norrie.

The Britain finds himself behind for the third straight service game but rattles off three points in a row to take charge.

A wayward backhand slice from Sebastian Korda gives the 30-year-old the hold.

Cameron Norrie will want this match to be sweaty and hard work, so I do think the best of five sets format will work for him today.

Sebastian Korda is the sort of player that can go through someone in a best of three sets format, but he's had issues doing it in Grand Slams in the past.

Barbora Krejcikova holds again, before Victoria Mboko does the same, albeit less convincingly.

Mboko is still under pressure on serve, and it's largely pressure of her own making. She's making too many errors at the moment.
