Batting first, England displayed their class with the willow, blowing away the Indian bowlers to put up 339/9 at the end of their 50 overs.
They were fuelled by a scintillating century from skipper Nat Sciver-Brunt, who made 122 off 105 – a knock laced with 13 fours and two sixes. Emma Lamb joined in with an attacking 81 off 59 down the order to help England set up a massive target.
Despite the best efforts of the Indian batters in the chase, led by a bright start at the top from Uma Chetry (45) and a crucial 66-run knock from Jemimah Rodrigues, the home side faltered down the order and fell to a mammoth 152-run defeat.
India next face New Zealand on Saturday, September 27 in their second and final warm-up clash. England and Australia lock horns on Sunday in a blockbuster warm-up fixture just ahead of the tournament opener on September 30.
