Needing three off the last ball, Morgan hit Ashok Dinda for a straight six to seal the match in England`s favour by six wickets at the Wankhede Stadium.
England required nine off the last over, thanks to the 26-year-old Morgan`s relentless onslaught that saw him smash five fours and two sixes.
Chasing a challenging target of 178, England were provided a blistering start by openers Michael Lumb and Alex Hales, who put on 80 runs for the first wicket in just over eight overs.
Lumb smashed 50 off a mere 34 balls while Hales made 42 off 33. But after their efforts, the show belonged to Morgan.
England needed 23 off the last two overs and managed 14 of them against Parvinder Awana.
