Ireland's batsmen let their side down as Somerset cruised to a 73-run victory that leaves their hosts rooted to bottom of the C&G Trophy South Conference.
Somerset won the toss and elected to bat and despite losing opener Matthew Wood early on, their top order batsmen built a solid total without any single batsman really shining in Belfast.
Andre Botha was the pick of Ireland's bowlers with impressive figures of 32 for three from his nine overs and he claimed the wicket of Somerset dangerman Justin Langer.
The Australian opener was beginning to settle at the crease and increase his run tempo when he edged a well-pitched delivery to wicketkeeper Gary Wilson.
Arul Suppiah went tamely for 22, bowled by Kevin O'Brien, as the visitors' top order continued to surrender their wickets when well set.
Cameron White and Keith Parsons settled any nerves with a fourth-wicket 58-run partnership, the best Somerset could muster.
With the exception of one mighty six, White played the conservative anchor role, spending well over one hour at the crease before he was stumped by Wilson, off the bowling of Kyle McCallan, for 38.
Man of the match Parsons top-scored with a patient 45, he also fell victim to the lively McCallan, while James Hildreth provided able assistance, until he was despatched by Botha for a quick-fire 36.
Somerset's lower order steered their total towards respectability as Ireland's bowlers struggled on a Stormont pitch with the visitors finishing on 238 for eight.
It appeared to be an attainable target for Ireland but, once again, their top order let them down.
Three of the top six failed to muster more than nine runs between them as Somerset's bowlers conspired to prevent their run chase gathering any momentum.
William Porterfield and Jeremy Bray put on 44 runs for the first wicket before the latter was caught by Hildreth off the bowling of former England Test player Richard Johnson.
And it was not long before his opening partner joined him back in the pavilion, although not before Wilson came and went after facing just six balls.
Botha failed to follow his impressive bowling performance with the bat, the South African all-rounder faced his share of balls for his miserly four runs but failed to read a Gareth Andrew delivery that uprooted his stumps.
Trent Johnston's dismissal not long after left Ireland 79 for five and reeling.
The lower order restored some pride with both Andrew White and McCallan producing performances at the crease, which will have embarrassed those higher up the order.
The duo's seventh-wicket stand of 47 was the best Ireland could produce before McCallan, on 28, was stumped by an alert Carl Gazzard, off the bowling of Parsons.
Parsons enjoyed his late spell with the ball, rattling through Ireland's final few wickets to secure the victory, earning figures of three for 24.
