England wrapped up a miserable tour for Sri Lanka as Jos Buttler guided the hosts to an eight-wicket win in the sole Twenty20 clash in Southampton on Tuesday.
Chasing a meagre 141 to win, England cruised home with 15 balls to spare as Buttler struck 73 off 49 - including four sixes - to set a new international personal best score in the shortest form of the game, although they were helped by another indifferent Sri Lanka display.
The tourists - who have failed to beat England in any format during the tour - struggled to build on starts in their innings and made a series of bad mistakes as Liam Dawson had a debut to remember, the spinner taking 3-27 on his home ground.
England were even able to lose Jason Roy (0) and James Vince (16) cheaply and still claim the win, Buttler supported by captain Eoin Morgan (47no) in a match-winning stand of 114.
Having won the toss and elected to bat, Sri Lanka struggled to build momentum as poor shot selection cost them dearly, Angelo Mathews (11) particularly at fault as he missed as slog sweep against Dawson.
Once the left-armer had removed three of the top four, it was Chris Jordan (3-29) who took centre stage with three wickets of his own, while England were sharp in the field.
Dasun Shanaka (1) and Ramith Rambukwella (19) were both run out in comedy circumstances, neither man making their ground in ambitious attempts to keep the scoreboard ticking over.
Jordan wrapped things up with the last ball of the innings, Sri Lanka's 140 all out never looking large enough to challenge England's big hitters.
And so it proved as Buttler - promoted to opener - flourished despite seeing Roy and Vince depart early.
He found a willing partner in Morgan as they bludgeoned their way to a comprehensive victory, the latter enjoying a slice of luck when he was dropped by Mathews at backward point.
Sixes were launched to all corners by both, Buttler - who was dropped by England's media manager in the crowd when clearing the ropes on one occasion - leading the charge superbly, before Morgan massive maximum completed the win.
Victory sees England wrap up a clean sweep, the hosts running out 20-4 winners in the Super Series format.
