Novak Djokovic faces Alexander Zverev in the last match on Rod Laver Arena today.

DJOKOVIC 6-7(6), 6-2, 6-4, 7-6(6) ZVEREV: Djokovic wins the first point against the serve in this tie-break to get his second match point, and this time he sends down an ace to wrap it up and get his place in the semi-final.

DJOKOVIC 6-7(6), 6-2, 6-4, 6-6 ZVEREV: Djokovic is always good on the stretch, and reaches a brilliant one-hander to take himself to game point. Zverev gets himself back in it with a gentle dink over the net but he can't close it out - it's another tie-break.

DJOKOVIC 6-7(6), 6-2, 6-4, 5-6 ZVEREV: A love service game for Zverev this time, as Djokovic complains about something, possibly his lack of pace on the ball.

DJOKOVIC 6-7(6), 6-2, 6-4, 5-5 ZVEREV: An absolute belter of an ace from Djokovic to see off the Zverev pressure and secure his serve.

DJOKOVIC 6-7(6), 6-2, 6-4, 4-5 ZVEREV: Djokovic does a couple of air backhands, to indicate what he has been intending to do, but doesn't pull off in this game at all.

DJOKOVIC 6-7(6), 6-2, 6-4, 4-4 ZVEREV: Two break points saved by Djokovic and that's a valuable hold.

DJOKOVIC 6-7(6), 6-2, 6-4, 3-4 ZVEREV: The ship is steadied as Zverev improves his first serve, sending it down at 200kmph.

DJOKOVIC 6-7(6), 6-2, 6-4, 3-3 ZVEREV: The crucial hold from Djokovic to level up! Can Zverev do the same? He's not managed a single ace so far this set.

DJOKOVIC 6-7(6), 6-2, 6-4, 2-3 ZVEREV: Zverev's stomach is taped up as well, you can see it as he stretches on serve, and his first serve is very shaky in this game. Djokovic is coming out on top in the lengthy rallies.

DJOKOVIC 6-7(6), 6-2, 6-4, 1-3 ZVEREV: Djokovic is really glaring at his team whenever he gets the opportunity. He gets on the board in this fourth but is playing much like he did in the first.

DJOKOVIC 6-7(6), 6-2, 6-4, 0-3 ZVEREV: This is a massive stroke of luck for Zverev, who twice serves double-faults and hands Djokovic break points, but he manages to recover to hold.

DJOKOVIC 6-7(6), 6-2, 6-4, 0-2 ZVEREV: Djokovic is so angry at the end of this game that he shapes to hit a ball in rage, then realised that didn't go so well the last time he did it, and stops.

DJOKOVIC 6-7(6), 6-2, 6-4, 0-1 ZVEREV: The German finally recovers his serve to hold at the start of the third.

DJOKOVIC 6-7(6), 6-2, 6-4 ZVEREV: Djokovic pushes his serve into the corner and Zverev gets nowhere near it, bringing up two set points. The German hits a return long on the Djokovic forehand, and that's the third set - and five games in a row.

DJOKOVIC 6-7(6), 6-2, 5-4 ZVEREV: A break to love for Djokovic. Zverev is laughing in disgust.

DJOKOVIC 6-7(6), 6-2, 4-4 ZVEREV: And once again this entire match turns round. Zverev may as well not be there at the moment.

DJOKOVIC 6-7(6), 6-2, 3-4 ZVEREV: And Djokovic breaks the Zverev serve. He's not playing particularly well and Zverev really ought to be putting him to the sword here.

DJOKOVIC 6-7(6), 6-2, 2-4 ZVEREV: And after that bit of chaos, Djokovic is calm once more to hold serve.
