All getting a little nervy in here. There were shrieks and gasps from the home fans during that tense rally on Barty's second break point. But nothing quite as loud as the Collins roars which are being let out at a much more frequent pace now.

I actually think that Collins has calmed down over the years. Obviously you can get rowdy on court if you are playing for your college. People took a while to warm to it, but she's calmed it down a lot.

That's how Barty moves through some of her opponents. They can stick with her and then she just creates that other level.
It poses a big question to Collins - can she find something? Can she manage two straight sets against a world number one?
