Good evening everyone! I can't quite believe we're at the semi-final stage already, but here we are! Up first tonight we have Angelique Kerber v Madison Keys, which I will be taking you through, and later on in the night session, we'll have coverage of Roger Federer v Tomas Berdych. Perfect, right?

Players are scheduled to get on court in around 10 minutes time, so get yourself comfy, and settle in for some top quality tennis!

These two couldn't have had more contrasting QF victories, with Keys giving Garcia a beatdown, but Kerber being pushed in a tight three-set encounter against Hsieh. What will tonight bring?

The players are just ready to come onto court. Feel free to leave any predictions you have below, just click on the 'be first' at the right of the text! I'm going to go for a Kerber win, but I'm not sure how many sets we'll see...

Kerber walks out first, followed by Keys, and there's plenty of support for both, which is lovely to see!

Contrastingly to the lovely sun in Melbourne, it's blowing a gale outside my house. How the other half live, eh?

Keys wins the coin toss, and chooses to serve. Warm-up time!

So the head-to-head is 6-1 in Kerber's favour, with their last meeting being a win for Kerber at the WTA Finals in 2016, which was Kerber's best year on tour!

Here we go, Keys to serve.

Good return from Kerber to put the pressure on Keys straight away, and she fires wide; 0-15. Keys hits a backhand into the net; 0-30. Oh dear, another good return from Kerber, and it's a Keys forehand into the net for THREE BREAK POINTS.
