|Fourth one-day international, Dubai|
|England 355-5 (50 overs): Buttler 116*, Roy 102|
|Pakistan 271 (40.4 overs): Malik 52, Moeen 3-53|
|England won by 84 runs|
Jos Buttler hit England's fastest one-day international century to lead them to an 84-run win over Pakistan in Dubai and a 3-1 series victory.
Buttler reached three figures in 46 balls, beating the 61-ball hundred he made against Sri Lanka in May 2014.
The wicketkeeper hit 10 fours and eight sixes in his 116 not out from 52 balls as England posted 355-5.
Pakistan briefly threatened a thrilling chase, but were bowled out for 271, with Moeen Ali taking 3-53.
Buttler's effort was the joint-seventh fastest in the history of ODI cricket and the quickest against Pakistan.
He has now scored the three fastest England centuries in the 50-over game, along with a 66-ball hundred against New Zealand in June.
That was Buttler's last score of 50 or more in all international cricket, a run of poor form that saw him dropped from the Test side for the third match against Pakistan this month.
The record for the fastest hundred in ODIs is the 31-ball effort of South Africa's AB de Villiers made against West Indies in Johannesburg in January this year.
Story of the innings...
Buttler's display of devastating hitting was all the more remarkable considering he did not arrive at the crease until the 36th over.
Promoted to number four after England were given a solid start by Jason Roy's maiden international century (102) and Joe Root's 71, the right-hander wasted little time in signalling his intentions, slog-sweeping Shoaib Malik for six from only the 10th ball he faced.
Brute force over the leg side was a feature of the 25-year-old's innings, with six of his eight sixes clearing the ropes in the direction of deep mid-wicket.
He also showed flashes of ingenuity, playing scoop and ramp shots, as well as one incredible reverse-sweep for four off the pace of Anwar Ali without needing to move his feet.
Anwar was again the bowler when Buttler moved to a century with his third six in four deliveries.
In all, he hit 17 of the last 34 balls he faced to the boundary and went from 50 to 100 in only 16 deliveries as England added 129 runs in the last 10 overs.
...in an entertaining game
Buttler stole the show, but his star turn was crammed into a 15-over period of an entertaining series finale.
Right-hander Roy overcame some early frailty outside off stump to reach his first ODI hundred in his 15th match, an innings that accelerated with straight and on-drives.
Support came from Root, who was at his free-scoring best until he fell seven runs after Roy was caught at long-off. That was part of a brief Pakistan period of pressure, one which halted by Buttler's brilliance.
Still, on a pitch perfect for batting, the hosts showed the will to chase their huge target, with captain Azhar Ali making 44 from 32 balls, Babar Azam a run-a-ball 51 and Malik most impressive for a 34-ball 52.
However, wickets fell too regularly for the hosts to ever be truly in contention. Mohammad Hafeez was run out in calamitous circumstances and almost all of the rest holed out.
In the end, what is only England's third ODI series win since February 2013 was sealed in comfort.
- Buttler is only the third batsman to score two ODI hundreds coming in to bat after the 25th over of the innings. AB de Villiers (five) and Virat Kohli (two) are the others
- Buttler's strike-rate of 223.07 is the highest for any England batsman in an innings of 50 or more
- His eight sixes is the most by an England batsman in an ODI innings, beating the seven of Andrew Flintoff against West Indies in 2004
- England have scored six ODI centuries in 73 balls or fewer in the past 18 months; they managed only one in 33 years before that
- Fastest ODI century against Pakistan (beating Sanath Jayasuriya's 48-ball ton for Sri Lanka in 1996)
- First England player to score 100 runs in overs 41-50 of an ODI (also achieved by De Villiers and Rohit Sharma)
- Highest ODI team total at Dubai (beating South Africa's 317-5 in November 2010). It is also England's highest score outside England and their fifth-best overall

'Buttler is a superstar' - what they said
Former England off-spinner Vic Marks: "Even the top players on that England balcony will be thinking 'I don't know how he does that'. You can understand why England, even when Buttler's going through a sticky patch in white-ball cricket, keep him in the side as when he clicks he's astonishing. The magic has returned.
"We shouldn't forget Jason Roy's hundred - the top three put England in a position where they could send Buttler out like that."
England batsman Jason Roy: "I don't really know what we've just witnessed. It was incredible."
