The visitors, who opted to chase after winning the toss, were helped by a wayward Indian bowling attack and a shoddy fielding display that enabled the openers to score quick runs.
Apart from Lumb who hit six fours and two sixes - and Hales, who had made a quick-fire 56 off 35 balls in the first match, skipper Morgan and Jos Butler (15 off seven balls) contributed significantly to England`s successful run-chase on a good batting track.
For India, Yuvraj Singh was the lone bowler to succeed with another excellent spell of three for 17, following his match-winning effort of three for 19 in the first match at Pune where England lost by five wickets.
Yuvraj got the wickets of the two openers and Luke Wright (5), but did not get the desired support from the other bowlers. The worst performers were Awana and Piyush Chawla.
England would now depart for home before returning for the five-match ODI series, commencing at Rajkot on January 11.
