Kieron Pollard bludgeoned a limited Ireland attack all around Mohali to muscle his side to a tall total. Pollard's effort helped to quell the criticism over his lack of performances at the international level, and gave West Indies' their third win in four matches, putting them in prime position for a quarter-final spot.
The batsmen gambled by taking the batting Powerplay then; a wicket at that stage could have scuppered the innings, but Ireland couldn't make the vital breakthrough and were helpless as the power of Pollard helped ransack 55 runs in five overs to shift the balance of the game.
Ireland had two opportunities to remove Pollard in the Powerplay: John Mooney narrowly missed a direct hit from square leg when Pollard had given up hope of making his ground in the 37th over, and Gary Wilson shelled a catch at long-on after hurtling across to get to a skier in the next over.
Over the next 45 minutes Pollard made them regret those misses with his now familiar brand of hitting, mainly muscling boundaries in the arc between long-on and midwicket. Boyd Rankin, Ireland's quickest, was brought in to handcuff Pollard, but his short ball was walloped to midwicket and an attempted yorker was pummeled down the ground. Rankin was rattled by the ferocity of the second hit, muttering to himself as his fractional mistake was punished.
A drive to midwicket in the 42nd over brought up Pollard's half-century off 35 balls - he celebrated by kissing an arm band bearing the injured allrounder Dwayne Bravo's number - but he was just warming up. The wickets tumbled at the other end, but there was no stopping Pollard, who capped a frenzy of hitting with 20 runs of an O'Brien over, which included a monstrous one-handed six that easily sailed over deep midwicket.
