Normal service was resumed after the highlight of Ireland's Twenty20 win over the West Indies last week with the calypso kings winning the only one-day international last night by four wickets with more than 13 overs to spare.
Ireland just didn't have enough runs on the board on a much better Sabina Park pitch, with in-form Gary Wilson's fighting half-century and good support by Stuart Thompson nudging his side through the 200 barrier, but that was the bare minimum required.
When West Indies openers Dwayne Smith and Kieron Powell put on a stand of 100 in less than 17 overs, it then became a damage limitation exercise for William Porterfield.
Dwayne Bravo hit an impressive 35 off just 29 balls and Marlon Samuels helped see the West Indies home with 26 not out off 21 deliveries.
The tourists, who will now head home today for a five-day break before they fly out to Dubai for a training camp, ahead of next month's World Twenty20 championships, were unable to choose Andy McBrine, who had impressed in the 50 overs competition in Trinidad, because of a finger injury.
Paul Stirling did a reasonable job in support of lead spinner George Dockrell, but although Stuart Thompson broke the opening stand and followed that up with a second wicket, Ireland just did not have enough runs to play with.
Again Stirling went early and although Porterfield enjoyed a life before he had scored, he failed to take full advantage of that and was caught down the leg side immediately after hitting two sixes off free hits.
The loss of Ed Joyce, Niall O'Brien, recalled in place of Alex Cusack, Kevin O'Brien and Andrew Poynter for just 65 runs, which used up 20 overs, was the deathknell for Ireland's hopes of a competitive total.
SCORING: IRELAND 202 (49.2 overs, G Wilson 62, S Thompson 33, W Porterfield 25, E Joyce 25, K O'Brien 22; J Holder 3-34, DJ Bravo 3-36, N Miller 2-30).
WEST INDIES 205-6 (36.4 overs, K Powell 57, D Smith 50, DJ Bravo 35; M Samuels 26 not out; S Thompson 2-17).
West Indies won by four wickets.
