Kenny Miller marked his first outing as Scotland captain with a goal as Northern Ireland were overwhelmed 3-0 in the Carling Nations Cup.
The Bursaspor striker, skipper for the evening, set Scotland on the way to a convincing win over a poor Northern Irish side at Dublin's Aviva Stadium.
James McArthur, a late addition to the side, doubled the advantage when an apparent cross drifted in and Kris Commons added a third early in the second half.
This comprehensive defeat must have been a demoralising experience for manager Nigel Worthington, who was working with more meagre than usual resources given the 10 call-offs from his original squad including one late withdrawal, George McCartney, who had apparently quit international football
In the 10th minute Scotland goalkeeper Allan McGregor had to deal with a low drive from Niall McGinn, who had been put through by fellow Celtic team-mate Paddy McCourt.
Four minutes later, however, the Scots should have been ahead. Celtic wide-man Commons forced his way into the Irish box before cutting the ball back to Miller - who had taken over the captaincy from injured Manchester United midfielder Darren Ferguson - but he blasted over the bar from 12 yards.
However, in the 18th minute the former Rangers striker made up for that miss when he put the Scots ahead. When Charlie Adam's corner came in from the left, Northern Ireland goalkeeper Jonathan Tuffey and skipper Stephen Craigan failed to deal with Phil Bardsley's near-post flick and Miller gratefully slammed the ball in from three yards.
The second Scotland goal arrived in the 31st minute although there was some doubt over McArthur's intentions after he took a pass from right-back Alan Hutton just outside the box. The former Hamilton midfielder appeared to be sending a cross over to the back post but he watched it sail over Tuffey's head and in under the bar.
The Scots fans celebrated the third goal in the 51st minute when Commons slid the ball past Tuffey after Old Firm rival Steven Naismith had set him up.
In the 83rd minute Rory Patterson should have scored a consolation for the Irish, but his close-range header lacked the power to beat McGregor and the game gradually petered out.
