    Now Coco has settled into the match and there's more tension. Potapova is displaying some dramatics and making some strange decisions on court.

    Yet again, Potapova goes for a backhand cross-court shot and it doesn't go her way.

    Potapova then goes long and Gauff breaks again!

    Anastasia apologises for a mishit - an error from her backhand which lands inside the tramlines.

    Is the Russian is feeling the pressure though? She hits a close-range shot straight into the net.

    She's certainly a lot less vocal than she was in the first set.

    30-30.

    That was a good angle from Coco but it was a rush of blood from Potapova. She went for the line winner and didn't even find the blue part of the court! If I was Coco, I'd look down at the other side of the court and realise that was too very bizarre shot choices. Her opponent is feeling the pressure.

    She's certainly providing a bit of variety here at the Louis Armstrong stadium. Potapova smashes a return wide, with the open court gaping.

    It gives Gauff the lead again. She's not giving up!

    Potapova 6-3 2-2 Gauff*

    It looks like the nerves could be getting the better of 15-year-old Coco Gauff now.

    She seems lethargic and is struggling with her serves. It's back-to-back double faults now for the American.

    Has she got it in her to come back fighting?

    We've seen it before! Will we see it again?

    Potapova 6-3 2-2 Gauff*

    Gauff stretches for a backhand and sends it cross-court. Potapova hits it into the net.

    The Russian pulls it back to 2-2, though.

    Gauff is going through every emotion here!

    A brilliant Potapova forehand.

    It's too much for Coco and the Russian takes an early 15-0 lead.

    Potapova just keeps impressing with her forehands.

    Gauff is left dumbfounded and it's 30-30.

    Potapova has already hit six forehand winners in this match. But she's being made to work hard now by Coco.

    Another sneaky drop shot from Gauff which came out of nowhere.

    Potapova wasn't expecting it, and can only hit the ball into the net.

    That is a huge game for Coco. She hustled a few points in defence mode. That's what she can do to opponents because she moves so well. Let's see if she can settle and take the lead. The crowd will then really get behind her.

    Huge amount of credit goes to Potapova here. She plays one smart point to get herself out of trouble then two huge strokes!

    No way Jose.

    A deep backhand from Potapova is too much for Gauff, who drives the ball into the net.

    Deuce.

    The Russian is unfazed, and pulls it back.

    Coco now has just the one break point.

    *Potapova 6-3 1-0 Gauff

    Woah! Potapova stretches as far as she can to reach the shot, and ends up screaming and doing the splits on court.

    Three break points for Coco.

    It's tough when it goes quiet like this. This crowd has to keep going. Coco is so young and needs some help right now as it's a new experience.

    A beautiful little drop shot there from Coco as she takes a 30-0 lead.
