The Scots had gone into the match seeking revenge for the heart-breaking last-over reverse on Friday while also aiming to confirm that they can be a consistent match for an Irish side which has dominated associate cricket in recent seasons.
Instead, Preston Mommsen's men appeared to be suffering from an emotional hangover, still hurting from the realisation that the slim possibility of automatic World Cup qualification had been lost 48 hours earlier.
Despite a damp outfield and a dry wicket, Mommsen had sufficient belief in his men to bat first, but a total of just 165 suggested that his confidence might have been misplaced. In contrast, Ireland, albeit in easier conditions, raced to their target with almost embarrassing ease, having 17 overs to spare when the winning run was scored.
It had started well enough for the visitors when Hamish Gardiner stroked consecutive boundaries off Max Sorensen, but there was to be little sustained hitting from the Scots, who received their first setback when Freddie Coleman was trapped in front by Sorensen for a single.
Gardiner's early flurry was brought to an end when, having reached 18, he feathered a catch behind off Eddie Richardson. Now, Scotland needed a big partnership from Matt Machan and Mommsen, who had stroked a fine unbeaten 91 in Friday's encounter. Instead, Machan's frustrating propensity for easing himself in only to fail to convert struck again when he departed for 23 with two boundaries, Niall O'Brien taking the catch off his brother Kevin's bowling.
O'Brien's medium pace was to do the most damage to Scotland's middle order and he struck an even bigger blow when he found the edge of Mommsen's bat and Gary Wilson gobbled up the catch. It was left to Calum MacLeod and Richie Berrington to provide the one meaningful partnership and even that was a moderate 66 runs from a painstaking 123 deliveries. David Murphy finished unbeaten on 20 while the rest went for single figures as the Scots were bowled out with three balls of their allocation remaining.
There were early signs that the Irish would find batting just as problematic, especially when Iain Wardlaw bowled the in-form William Porterfield for five and then had Paul Stirling caught behind to reduce the hosts to 22 for two. However, Ed Joyce and Niall O'Brien showed all their one-day international experience in a solid 69-run stand that put their side in the driving seat.
Joyce had stroked six boundaries when he was deceived by Majid Haq and bowled for 39 but O'Brien was still there at the end, having moved through the gears to finish on 65 at almost a run a ball.
Gary Wilson, lent support with a composed 35 which included four boundaries and the only 6 of the game.
Mommsen was quick to acknowledge the flaws which undermined Scotland's hopes of securing the two wins they needed to retain hopes of automatic World Cup qualification.
"We have played some good cricket over the two matches but unfortunately nobody was able to go on and make the big score that was needed," he said. "Plenty batsmen got starts but you have to take advantage of that. We obviously need to regroup again, but we still have an opportunity to go to the World Cup with the qualifying tournament in New Zealand."
