An electric knock from Jos Buttler and David Willey's brilliance with the ball piled the misery on Sri Lanka as England secured a 122-run victory in the fifth and final one-day international in Cardiff on Saturday.
Although the ODI series was already wrapped up with England already in possession of an unassailable 2-0 lead, Buttler launched a late surge to help the hosts post a commanding 324-7.
Buttler produced an array of shots with typical flamboyance, notching a 35-ball fifty on his way to a total of 70 as part of a formidable 109-run partnership with Joe Root (93).
Sri Lanka's response was consistently punctuated by the fall of wickets, Willey claiming the first and last as part of a four-wicket haul at the cost of just 34 runs that saw the tourists bowled out for 202 in a match the hosts dominated.
Jason Roy's magnificent 162 had inspired England's victory in the fourth ODI at The Oval but, after an early rain delay, he made just 34 before being caught in the deep off Suranga Lakmal (1-65)
James Vince notched his first ODI half-century but was stumped off Danushka Gunathilaka (3-48) for 51, but Root kept England ticking along.
The number three showed great judgement with his running, regularly picking up singles as Sri Lanka were punished for the absence of Angelo Mathews in their bowling attack due to a hamstring injury.
Buttler set the tone in the 34th over with a sweet shot to the fine-leg boundary first ball, making 25 runs off the first 25 deliveries faced.
The wicketkeeper-batsman needed just 10 more to make his half-century, scooping Nuwan Pradeep (1-59) behind for a four before crunching a six off Lakmal over wide long-off.
Chaminda Bandara (1-83) finally secured his maiden ODI wicket when he dismissed Buttler with a yorker, and Root, dropped inexplicably by Lakmal soon after, followed in the final over.
Liam Plunkett (9) and Chris Woakes (17) added the finishing touches, and Sri Lanka's hopes of chasing down 325 took an early blow when Kusal Perera (6) was given lbw off Willey.
Jonny Bairstow and Buttler combined to run out Kusal Mendis (22), before Danushka (48) was trapped leg before by Plunkett (3-44).
Dinesh Chandimal struck 53 to provide some consistency for the tourists, but their approach was lacking in aggression and always looked likely to fall short of the target.
After Chandimal missed a delivery from Willey that crashed into middle stump, Sri Lanka were 195-9 with just 54 balls remaining.
And 16 deliveries later the match was over, Pradeep lofting Willey to Woakes at mid-on as England wrapped up a 3-0 series victory in fine style.
Sri Lanka have one final chance to salvage some pride from the tour in Tuesday's only Twenty20 International in Southampton.
