Dellacqua and Barty on the board - down a break at 1-2.
Agassi: "Competing here... Did wonders for my blood pressure. I love coming back to this place."
It's not going so well for the Aussie girls on RLA - they've dropped the first set against Errani and Vinci 6-2.
Loving too how close Casey is with her family. They're out here in force at AO2013. Let's take a look at who's supporting the Aussie No.2 ...
Meanwhile, it's locked at 3-3 in the second set of the women's doubles final.
Huge cheer as Barty and Dellacqua serve out the game to take the second set 6-3. We're going to a third!
Casey and Ash break in the opening game, but the Italians break back to eventually move ahead 2-1.
Must say, absolutely LOVING Barty's backhand smash. She's played about four now and is evoking memories of fellow Queenslander Pat Rafter.
The Italians have broken to lead 4-2. Is this the end to the Aussies' Cinderella run?
Down 0-30, Errani and Vinci hold for 5-2. They're growing in confidence .....
Murray wins the toss and elects to take a side of the court over choosing whether to serve or not. Interesting.
With Djokovic, Federer, Murray and Ferrer being the four semifinalists here, it's just the 15th time in the Open Era that the top four seeds have been the last remaining. The last time it happened? AO2012.
Looks like we won't be getting a glimpse at Mirka or the Roger Federer box tonight... a jacket was just put over the camera that peers into their part of the crowd - by one of the members of the box. Overheard in media: Is that legal? Good question.
Welcome to the Popcorn live blog, all! We've got Federer and Murray in the second of two men's semifinals. Vote in the poll below on what you think this match holds tonight.
A 28-stroke rally goes the way of Murray and he has a break point on Federer serve from the get go!
Federer saves a break point and has a 1-0 lead after 4 minutes. Murray to serve.
Though Murray has a 10-9 overall record against the Mighty Fed, he's 0-3 against him in majors. This is the first time they've met before a final, however. US Open 2008, Australian Open 2010 and Wimbledon 2012
After Murray holds he hops out to a 15-40 lead on Federer's serve. Roger saves one, 30-40
