Azarenka wins 6-1, 6-4.

An incredible second set from both players, with Sloane Stephens surviving five match points, but could not hold serve against Victoria Azarenka's powerful game.

We'll no doubt see plenty from Stephens throughout her career, who has shown here at the Australian Open that she is a real talent for the future.

Azarenka, on the other hand, deserves full credit for fighting through injury and perhaps some mental fatigue to book her place in her second straight Australian Open final.

The crowd is definitely behind Stephens here, with Azarenka getting very frustrated at herself and her inability to find the winners she once had.

Stephens continues to make easy mistakes, though, which is keeping Vika alive.

TWEET, TWEET.

Azarenka holds for 3-2. Don't think her ankle tweak was major. No visible pain beyond that one moment, and no trainer visit. #ausopen
