Six - straight into the hands of an Ireland supporter. Back to back boundaries put Ireland in such a strong position.
This is carnage.
Andy Balbirnie dispatches Odean Smith's first three balls for four, six, four - and West Indies are completely unravelling.
Paul Stirling looks like he is batting on a completely different pitch! He effortlessly slots Alzarri Joseph into the stands and Ireland are racing.
Nicholas Pooran has to turn to his strike man Alzarri Joseph early.
He bowls quick and hits Paul Stirling in a very uncomfortable place. Stirling sinks to his knees and calls for a drink.
Not even a smile from Joseph, he's in the zone.

What a good start this has been. Ireland getting exactly the start they wanted.
Target 147
Same shot, four runs this time to Paul Stirling! 16 from Akeal Hosein's first over and West Indies are under real pressure after just two overs.
Oh, what a shot!
Andy Balbirnie gets down on one knee and slog sweeps Akeal Hosein for six!
Ireland's ideal start continues.
Target 147
The perfect start for Ireland as Paul Stirling gets the first boundary via a thick outside edge as Obed McCoy gives him too much width.
He is a dangerous batter and West Indies would love to get him out early.
Odean Smith says that he backs their bowlers, but believes the total is "way under par".
Ireland chased down 176 against Scotland on Wednesday so they will be full of confidence.

Ireland will be delighted with that. They'll take so much confidence from the mammoth run chase from the other day.
Gareth Delany was the star with the ball for Ireland, taking 3-16 from his four overs.
A wicket each for Barry McCarthy and Simi Singh and they will be happy with that effort at the halfway stage.
Oh, interesting. It looks like a guaranteed wide from Mark Adair but the umpire doesn't give it, suggesting that Odean Smith had moved across his stumps. The batter is furious, but nothing he can do.
West Indies complete their innings and Ireland need 147 to win.
Brandon King finishes unbeaten on 62 from 48 balls.
A big swipe from Odean Smith and the ball flies off the outside edge for another valuable four. One ball to go...
Smith does very well, just sliding his back in perfectly. Two precious runs and the big hitter is back on strike.
The batters try and come back for two after Odean Smith smashes one out to cover, but has he been run out? It looks close.
There's the first! Mark Adair bowls a full toss and Odean Smith gratefully accepts.
A huge six, 106 metres. Pressure on Adair and Ireland.

West Indies are going to have a big over here. 45 dot balls is far too many.
10 runs from that over.
One to go. It doesn't quite feel enough at the moment, so West Indies could do with a few boundaries from it.
Some very welcome runs here for West Indies as Brandon King smashes Barry McCarthy into the stands over mid-wicket.
Great shot.
