Ireland slumped to a seven-wicket loss against Trinidad & Tobago 'B' in their latest warm-up match before facing West Indies in the Caribbean.
Having been put it to bat, openers William Porterfield and Paul Stirling added 49 in just 33 balls before the skipper fell for 24.
Stirling continued in his usual belligerent style, hitting nine boundaries in the top score of 44 from just 27 balls.
After his dismissal the run rate slowed as Ireland found difficulty in scoring boundaries. Kevin O'Brien (9), Gary Wilson (5) and James Shannon (3) all fell cheaply.
Andrew Poynter made an unbeaten 27 from 33 balls, and Niall O'Brien's 19-not-out came from 18 deliveries; the Irish finished on 141-5.
Tim Murtagh (1-21) struck with his second ball, but Kjorn Ottley dominated a second wicket stand of 51 with Aaron Alfred (15), hitting 41 from just 27 balls (6 fours, 2 sixes).
Kevin O'Brien (1-23) and Andrew McBrine (1-16) struck in quick succession to bring Ireland right back into contention at 56 for 3.
However, an unbroken fourth wicket stand of 87 between skipper Justin Guillen (51*) and Daron Cruickshank (35*) saw the young Trinidad and Tobago team safely home with nine balls to spare.
Guillen's man-of-the-match unbeaten 51 occupied just 34 balls and included 5 fours and a six.
Cruickshank was content to play second fiddle, his undefeated 35 taking 37 balls and containing 4 boundaries.
Ireland fly to Jamaica on Saturday where they will play West Indies next week in two Twenty20 internationals and a solitary one-day international. These games take place on Wednesday, Friday and Sunday, respectively.
