The England cricketers have completed a clean sweep of their 2010 home series after beating Pakistan by 121 runs in the fifth and final one-day international at the Rosebowl in Southampton.
Pakistan, set 257 to win the match and the series, tumbled from 63 without loss to 135 all out in 37 overs.
Off-spinner Graeme Swann, a crucial figure in England's Ashes plans this year, gained prodigious turn to finish with three for 26 from nine overs.
Earlier Eion Morgan hit his 4th one day century.
During a long and tiring season to be followed soon by the Ashes defence in Australia, England beat Bangladesh and Pakistan in successive test series.
They won a one-day series against Australia and two Twenty20 matches against Pakistan followed by a 3-2 win in the five-match 50-overs series which was overshadowed by a corruption scandal which erupted in the final test at Lord's.
England's 16-man squad for the Ashes defence will be announced at Lord's tonight.
