England bowlers deliver again before Jason Roy's 61 seals successive wins
Tymal Mills, Liam Livingstone and Moeen Ali shared seven wickets, as England dominated with the ball
Moeen's impact at the top of England's innings transformed the permutations for Morgan through the middle overs - particularly once it became apparent that the extra pace of Chris Jordan and - at that stage of the innings - Tymal Mills was offering a hint of a route back into the contest for Bangladesh. After conceding 12 and 11 runs respectively in their first forays, Morgan turned instead to the variations of Liam Livingstone, who skidded his third ball through Mushfiqur's attempted reverse-sweep and extracted a crucial breakthrough on review.
A minor dent to England's progress followed when Rashid, entrusted with one half of the death overs in a worthwhile experiment, was bludgeoned with some success by the left-hander Nasum Ahmed, who targeted the short leg-side boundary for the only two sixes of the innings.
England's only duff note against West Indies was the slight tangle they got in while trying to rush to their 56-run target. They made no such errors this time around. Jason Roy marked his 50th T20I cap with a rampant knock of 61 from 38 balls, his five fours and three sixes including a massive straight strike off Nasum to bring up his half-century. In adding 39 for the first wicket in 28 balls of the powerplay, he and Jos Buttler ended any fears of a twist in the tale.
