Salisbury and Ram go out in the men's doubles semi-finals
It has been a busy day all round on Day 11 - and here is what you missed from earlier today.
There will be no showdown with the Aussie combination of Nick Kyrgios and Thanasi Kokkinakis for Britain's Joe Salisbury and American partner Rajeev Ram as they fell at the semi-final hurdle.
'Facing Barty in final will be spectacular'
Collins 6-4 6-1 Swiatek
Here's what Danielle Collins had to say following her victory:
"It feels amazing. It has been such a journey. It is so many years of hard work. Yesterday I spoke about all the early mornings my Dad would get up and practice with me before school. It is incredible to be on this stage, especially after all the health challenges. I couldn't be happier.
"I have added more variety to my game over the last couple of years but this is my Plan A. It was working for me really well today so I just had to stick with it.
"Normally I sit down but for whatever reason in this competition I don't feel like I have time to sit down. I haven't sat down all tournament."
And on facing Ash Barty in Saturday's final, she added: "We've had some incredible battles over the years. To play the world number one in her home country will be spectacular. The energy the crowd will bring, whether it's for me or against me, it will be a incredible. I look forward to a great match."

This is absolutely phenomenal from Danielle Collins.
Almost no reaction from her after winning that match.
She's into a Grand Slam final - it looks like she could have just won a first round match.
There's more reaction from her box than from her.
Game, set and match - Calm and collected Collins through to the finals!

Swiatek steps up to try and hold off the inevitable, but the serve gets the same treatment it has been getting all night. Swiatek belts it long, and Danielle Collins is through to her first Grand Slam final in a remarkable display of focus.
Almost no reaction from her.

The first little hint of a smile on Swiatek's face.
She has to be thinking it has been unbelievable from Collins.

Collins 6-4 5-1 Swiatek*
Collins has been serving up a real storm - not necessarily all huge serving, but pin-point accuracy and Swiatek has had no chances at all to make a dent in it.
She bombs down a massive serve on game point which Swiatek does well to get to as it soars in the air.
Collins tracks it like a panther tracks its prey... and no messing about as she puts it away. She is a game away from her first Slam final.

That's why you fight until the end. You try and get everything you can in the tough moments.
If Iga Swiatek can get one of those breaks right here it would significantly change the match and the pressure Collins would feel.
It's not easy to keep your mind focused on the moment. How big this moment would be. How you've dreamed about it.

Now in the first set, Swiatek clawed herslef back into contention and made it a lot tighter than it started.
She tries to close down the court and cut off Collins' angles but another cross-court winner from the American takes her to 30-30.

Danielle Collins is not playing. It has been all business.
She is making Iga Swiatek look slow - and she is far from slow.
That is the intensity and speed with which Collins is playing these points at.
