Right, I'm off. Thanks for joining us for Murray's victory in Shanghai. There's more live sport in offer from the BBC in the shape of football, which you can find here.

I'll see thee.

Murray signs the TV camera - as is the now traditional way in tennis - to mark his victory and sixth title of the year. He has now won this tournament three times. It is going to take an awful lot to beat this fella now.

Novak Djokovic now has just 915 points buffering his world number one ranking.

And that is that. Murray takes the game to love, underlining his authority with some 100mph second serves and ground-strokes that Bautista Agut can't live with. He closes it out with an overhead smash. 

Bautista Agut is a broken man now as Murray's charge towards this title continues. The Scot somehow gets himself out of jam, chasing balls short of and over him to go 30-15 up before closing the game out with a lovely cross-court shot and an unforced error into the net from the Spaniard. The Scot is one away, serving for victory.

Consistently, Murray has more ideas once the two get deep into a rally. Bautista Agut has occasional moments of invention and power - as demonstrated by the neat drop shot and cross-court forehand that enable him to level up at 15-15 and 30-30. But when it really matters, Murray is making more shots and fewer errors.

Just as the window of opportunity sneaks open for Bautista Agut, Murray closes it again. The Scot loses the first point courtesy of another badly miscued forehand, but wins the next four - the last two coming from successive double-faults from the Spaniard. That is gonna sting.

Murray is not happy. He goes down 0-30 after failing to reach a ball on the umpire's side and takes the opportunity to suggest an early call for a first-serve review from Bautista Agut may have come a tad late.

He is even less happy when he loses the game. He manages to save one break point at 40-15 but makes an absolute hash of rescuing a second, hooking his shot horribly when he seemed to be an advantageous position centre court.

Bautista Agut is fading fast. After Murray wins the first point, the Spaniard has a huge chance to pull level but puts his volley wide with the whole court open to him. It is a huge moment as Murray is then able to close out the game through two further enforced errors.

This could be over very quickly now.

So, Murray is now 19-0 for sets in Beijing and Shanghai in 2016. He is quickly off in the pursuit of making that 20-0 with a strong service game. Bautista Agut wins his first point in a while courtesy of a powerful forehand to delay the inevitable and make it 40-15, but Murray responds with a soul-crushing ace.

Andy Murray's five titles in 2016:

ATP World Tour 1000 Masters Rome (beat Novak Djokovic 6-3 6-3 in final)

Aegon Championships/Queens (beat Milos Raonic 6-7 (5-7) 6-4 6-3 in final)

Wimbledon (beat Milos Raonic 6-4 7-6 (7-3) 7-6 (7-2) in final)

Rio Olympics (beat Juan Martin del Potro 7-5 4-6 6-2 7-5 in final)

China Open (beat Grigor Dimitrov 6-4 7-6 (7-2) in final)

Halfway there. Murray made much harder work of that first set than he needed to but he gets there in the end.

It is a testimony to his temperament and ability to shift through the gears. Bautista Agut simply couldn't live with the Scot in the tie-break.

Bautista Agut shows some fight in a long rally but Murray takes it as the Spaniard hits his forehand from the baseline into the net. The Scot gives himself five set points by winning a second long rally - Bautista Agut's backhand return floating wide.

This set is slipping away from Bautista Agut now.

Murray responds, winning both his service points - the first a brave cross-court backhand that Bautista Agut puts into the net, the second a wide serve the Spaniard can't return.

A misjudged attempted lob from Murray gives Bautista Agut the first point of the tie-break. 

Good response from Murray. He silences the fury in his own head with his own win to love. Three straight aces do the business.

Well, this match has turned around very quickly. Bautista Agut makes light work of the game, winning it to love. Murray still looks rattled by the previous game. He needs to clear his head quickly.

"Why?!!!" screams Murray. At himself. 

He looks to have the game in the bag at 40-15 but somehow engineers deuce following some pretty standard returns from Bautista Agut.

After cancelling his own ace out with a double fault, Murray then ill-advisedly charges in and is caught out at his own toes before Bautista Agut levels things up with a forehand. This Spaniard is not for folding.
