Ireland U17 skipper Neil Rock hit a brilliant 77 to lead his team to victory in the last match of the Celtic Cup series at Ayr.
The Rush left-hander hit 7 fours and 4 sixes in his 42-ball innings as the Boys In Green piled on the agony for the Old Enemy, racking up an impressive 211 for 5 in the T20 contest.
The tone for the onslaught was set by Instonians opener Ollie Metcalfe who clubbed 6 fours and 2 sixes in a 19-ball 42, as 51 came in the first three overs.
Max Burton (21) and James Hunter (21*) kept the momentum going in a super batting display by Nigel Jones' side.
Scotland never threatened to chase down the target, falling 50 short, with Tom Mackintosh making 44.
Mitchell Thompson and Cillian McDonnell took three wickets apiece, while Gregory McFaul claimed two in a fine al-round display.
This match completes the summer programme for the Irish youth teams, which has been a successful one by any standards.
