JJ Garth and Gareth Delany took a combined seven wickets as Ireland Academy beat their Scottish counterparts by seven wickets.
In a game reduced to 45 overs after early morning rain, Scotland made a fine start as Rory Johnston (54) and Finlay MacCreath (30) took them to 93 for 1.
However, leg-spinners JJ Garth (4-34), Gareth Delany (3-43), and opening bowler Rory Anders (2-11) saw the Irish roar back as the Scots wilted to 166 all out.
Delany (20) and Jack Tector got the Irish reply off to a fast start, adding 47 for the first wicket.
The Irish skipper hit 8 fours in his 52 from just 44 balls, adding a further 57 with Stephen Doheny (28).
Both then fell in quick succession along with Aaron Gillespie (4) to give Scotland some hope.
Any thoughts of a comeback though were quickly dispelled, as Harry Tector (27*) and Neil Rock (24*) closed out an emphatic six-wicket win.
The Irish Academy play their final game of the tour on Friday against the Future stars.
