Unbelievable start from Emma Raducanu, under half an hour, not dropped a game.
She has not allowed Rebecca Marino into this match at all.
It has been relentless from Raducanu so far.

Canada’s selection was less clearcut than Britain's choice.
Their captain Heidi El Tabakh decided to go with the experience of 33-year-old Rebecca Marino, who plays the bulk of her tennis on the second-tier tour these days, over the potential of teenager Marina Stakusic.
It feels like she has made a big mistake.
*Marino 0-6 0-0 Raducanu
Easy-peasy for Emma Raducanu, who wraps up the set with a dominant hold to love. She's on fire!
Great Britain captain Anne Keothavong couldn't have asked for anything better.
Marino 0-5 Raducanu*

Emma Raducanu just looks confident, really clear with what she is looking to do.
When she is needing to defend, she is happy to put balls back into play as well which is also important.
Marino 0-5 Raducanu*
And there's the third break for Emma Raducanu as Rebecca Marino sends a forehand long.
This could all be over very quickly.
*Marino 0-4 Raducanu
Emma Raducanu forces Rebecca Marino out wide with a big backhand before lashing home a forceful forehand winner, well out of her opponent's reach.
*Marino 0-4 Raducanu
A lovely little backhand lob gets Emma Raducanu off to a great start on Rebecca Marino's next service game.
The Canadian pulls ahead, but she isn't able to put the game to bed and we go to deuce as she pushes the ball into the net.

Raducanu's first serve was key in the opening set of her win over Germany's Jule Niemeier on Friday.
It was also very effective in her opening service game here.
The British number two says she has been working on making her serve "more of a weapon" and plans to focus on that more in the off-season.
Lengthening her takeback again, having gone to a shorter swing in the summer, is helping her find more rhythm and consistency. It also seems to be generating extra power.

Anon: Come on GB!! The match lineups make me more nervous. Katie v Rebecca & Emma v Leylah seemed like the best options but got my fingers crossed.
*Marino 0-4 Raducanu
Emma Raducanu falters with a double fault, but not for long.
The British number two responds with a hefty serve that Rebecca Marino is able to return - only for Raducanu to send a blistering cross-court winner away.
The Canadian mutters to herself angrily as a wayward shot into the crowd sees her fall to a 4-0 deficit.
Marino 0-3 Raducanu*

What a great start from Emma Raducanu.
She has been able to get through a match and at the moment Rebecca Marino has just been caught a little cold.
She hasn't been able to land her first serves.
Marino 0-3 Raducanu*
This time she gets it!
Rebecca Marino tries to send her opponent out wide, but Emma Raducanu replies with an angled forehand of her own and the Canadian can only find the net with her return.
Raducanu is flying.
*Marino 0-2 Raducanu
Rebecca Marino goes for the smash but misses, and it's another chance for Emma Raducanu to earn herself a 3-0 lead.
*Marino 0-2 Raducanu
Nope, says Rebecca Marino. The Canadian sets herself and strikes a booming forehand winner out of Raducanu's reach.
*Marino 0-2 Raducanu
Rebecca Marino saves the first, while Emma Raducanu pushes the second into the net.
But she's got herself another one. Third time lucky again?

You wondered how Raducanu would pull up today after playing her first match in two months on Friday.
Pretty well so far is the answer. She looks sharp in body and mind.
Big problems already for Marino.
*Marino 0-2 Raducanu
A series of superb slices from Emma Raducanu catch out Rebecca Marino before the British number two unleashes an overhead winner.
A unforced error from Marino offers two more break points for Raducanu.
*Marino 0-2 Raducanu
The serve was working wonders for Emma Raducanu on Friday and it looks like she has picked up exactly where she left off.
Three big serves and a Rebecca Marino unforced error help the Briton back up the break with a hold to love. A perfect start.
Marino 0-1 Raducanu*

The ideal start there and I think in some ways Emma Raducanu is probably quite pleased that Rebecca Marino started first, to impose herself and get a good strike on the serve to put some pressure on the Canadian.
