It has been a pretty uncomfortable day here, even for those of us not running around, and the temperature is still over 30C with humidity around 50%. Facing Wozniacki in such conditions is a bit of a nightmare, as a lot of running is required.
The heat rule is in play this evening I believe, so if we get to a third set, there will be a 10-minute break before the decider.

Halep also has the ice towel around her neck, and is taking on plenty of water.
I'm sure Caroline Wozniacki won't be too disappointed about having a breather either.
The world number one is back on her feet, Wozniacki to serve...
Halep 6-7 (2-7) 3-2 Wozniacki*
I think Simona Halep is saying she feels dizzy. She's having her blood pressure taken at the side of the court.
It's been a punishing one hour and 19 minutes in the Melbourne heat.

Efficient from Wozniacki, as far as games in this final go...

Halep was down 5-2 in the first and started accelerating through the ball more aggressively but this set has been a bit up and down.
She needs to do it more consistently and use the angles to keep Wozniacki on the run.

This game has passed the 10-minute mark, and it's Wozniack with a loose response this time that lands in the tramlines, just.
Advantage Halep.
Wozniacki can't get enough on another well-timed drop shot from the Romanian, she holds.
Composure when it matters.

Back to deuce.

That's aggressive from Simona Halep, shuffling forward with every exchange and taking advantage of a Caroline Wozniacki that loops into the air off the tape.
Deuce.
