*Murray 4-6 4-6 7-6 (7-5) 6-6 (5-1) Bautista Agut
Superb from Andy Murray!
A well-timed move to the net, he stretches, volleys - and wins the point!
This is unbelievable.

Superb from Andy Murray!
A well-timed move to the net, he stretches, volleys - and wins the point!
This is unbelievable.
*Murray 4-6 4-6 7-6 (7-5) 6-6 (4-1) Bautista Agut
Another rally dictated by Murray and Bautista Agut, steadying himself for the big cross-court winner, misses.
And now a backhand from the Spaniard drifts over the baseline! Murray extends his lead...

I don't think Bautista Agut's expression has changed for three and half hours despite the incredible atmosphere here and what's unfolding in front of him.
Murray 4-6 4-6 7-6 (7-5) 6-6 (2-1) Bautista Agut*
"No!" yells Murray as he shimmies forward and overworks his backhand.
And that's followed by a "come on!" as Bautista Agut's return of serve drifts long.
*Murray 4-6 4-6 7-6 (7-5) 6-6 (1-0) Bautista Agut
OH!
A terrific rally, and Murray comes out on top, a furious forehand bunted long by Bautista Agut.
David Law
BBC Radio 5 live tennis commentator at Melbourne Park
Murray doesn't care if he's carried out. He will scrap and fight for every ball.

How's the nerves, folks?
Roberto Bautista Agut will serve first.
Murray 4-6 4-6 7-6 (7-5) 6-6 Bautista Agut*
Bautista Agut nets the backhand!
Tie-break time!
*Murray 4-6 4-6 7-6 (7-5) 5-6 Bautista Agut
Fine, fine work from Murray, dictating the rally with his forehand before darting forward to volley a winner.
He's 30-0 up and then an unfortunate net cord hands him another point.
40-0...

Quite aptly there are fireworks outside. Presumably from the MCG, which is hosting Big Bash cricket tonight. Those rockets put Murray off momentarily... can he put another one up Bautista Agut?
*Murray 4-6 4-6 7-6 (7-5) 5-6 Bautista Agut
The fireworks at the MCG - the cricket ground down the road from Melbourne Park - are currently holding up Andy Murray's service game.
There's probably some irony there.
*Murray 4-6 4-6 7-6 (7-5) 5-6 Bautista Agut
Can Andy Murray force a tie-break?
We're about to find out...

What's most heartening, at least in my eyes, is seeing Murray still chuntering and cursing after every error. Classic Andy. And shows how much it means, how much he cares. As if we didn't already know.
*Murray 4-6 4-6 7-6 (7-5) 5-6 Bautista Agut
Andy Murray gets a bit too clever with a floaty drop shot and yells at himself as the ball gets battered by Roberto Bautista Agut.
Murray gets on the board as his opponent missed a forehand, but it's soon 40-15 to the Spaniard.
Wallop. Ace. Murray will serve, once again, to stay in the match.
Murray 4-6 4-6 7-6 (7-5) 5-5 Bautista Agut*
New balls, and Roberto Bautista Agut to serve with them.

Judy Murray's poker face is excellent.
Jamie, on the other hand, looks like he'd quite like to hide behind his chair.
Murray 4-6 4-6 7-6 (7-5) 5-5 Bautista Agut*
Andy Murray has just stayed in a rally that he had absolutely no right to, and won the point.
He was stumbling behind the baseline, unfurled the drop shot as a last ditch attempt - and Bautista Agut nets.
It's a love hold to Andy Murray.
*Murray 4-6 4-6 7-6 (7-5) 4-5 Bautista Agut
Here we go then.
Andy Murray will serve to stay in this match.
*Murray 4-6 4-6 7-6 (7-5) 4-5 Bautista Agut
A full-stretch Roberto Bautista Agut somehow gets his racquet onto a passing shot from Andy Murray, and he dinks a winner over.
Oh, and the Spaniard produces a superb passing shot of his own to go 30-0 up! Murray looks more than a touch irked.
A love hold.
