Captain Darren Sammy smashed 30 runs off just nine deliveries as the West Indies beat England by five wickets to take the Twenty20 series 2-0 with a game to spare.
Sammy's blitz ensured the hosts reached the 153-run target with seven balls to spare after Dwayne Smith and Chris Gayle had given them a 48-run opening stand in under five overs.
Tim Bresnan gave England hope of squaring the series with two wickets in two balls of the 17th over with the hosts needing 37 off 22 deliveries. However, Sammy blasted two fours and three sixes to confine England to their fifth Twenty20 loss in a row.
Earlier, Jos Buttler smashed 67 off 43 balls and Alex Hales 40 off 36 as England recovered from 18-3 to post a competitive 152-7 off their quota. Krishmar Santokie picked up 4-21 off his four overs as none of the other England batsmen were able to contribute significantly to the total.
The final match of the series takes place at Kensington Oval on Thursday.
