"The injury has just been enough to put Roanic off a little but Murray has piled the pressure on."
Murray 4-6 7-5 6-7 (4-7) 6-4 4-0 Raonic*
Andy Murray is like a small boy pulling the wings off a fly.
He drags Milos Raonic left and right at the back of the court, before testing the ailing Canadian's movement up court with a teasing drop-shot.
Raonic passes that test - just about scooping the ball off the deck.
His reward? A winning lob back over his head.
Murray takes pity with an ace closing out a game to love.
Russell Fuller
BBC tennis correspondent in Melbourne
"It's been a fabulous match but the injury to Raonic has just taken a little bit out of the occasion."

Marcus Adams: Raonic looks like a little boy who's just been told Christmas is cancelled...on the verge of tears.
Andrew Punton: Aarghh! Why do I have to leave to catch a train in the middle of this? Hopefully the wifi on the train lets me keep listening!

Bong! Bong! Bong!
The bell is tolling for Milos Raonic now.
The Canadian could well have been heading into the final but for a leg niggle. He is now a lame duck though.
It is going to take something truly heroic to divert Andy Murray from the winners' enclosure.

We'll always have that serve though Milos.
Raonic's 18th ace of the match takes him to 30-15 and he pairs up a big serve with a whopper of a forehand to advance to 40-15.
Murray is hot on his trail now though. The Scot takes it to deuce as he tries to smoke out a potentially fatal second break of serve in this decider.

Andy Murray whistles through a game to love. Milos Raonic is barely breaking past a jog.
And even Lady Luck is pulling against the Canadian with a net cord transforming a routine rallying shot into a deadly drop-shot on his side of the court.

"Raonic is in big trouble now. He returned well in the last set to get into games and got closer and closer to breaking, but with a sore leg it won't be any easier to break Murray.
*Murray 4-6 7-5 6-7 (4-7) 6-4 1-0 Raonic
Milos Raonic looks like he has cracked - physically, mentally, heck, probably spiritually.
The Canadian hands over a break of serve with a double fault at 15-40 down and looks badly hindered by a leg injury he picked up early in the fourth set.
Raonic reacts by turning graphite to splinters as he wrecks his racquet on the court floor.
Murray has been broken only once in the match - in the very first game.

Murray 4-6 7-5 6-7 (4-7) 6-4 Raonic*
Milos Raonic is the proverbial wounded animal.
The Canadian is lashing out with the bludgeon forehand as soon as he can in rallies, knowing that his movement is compromised by that leg injury.
He is in the last-chance saloon - but that might suit his power game.

Anthony Walton: It's tax return deadline time, trying to finish off last minute panic clients and keep up to date with the Murray. Rollercoaster!
