Hull's teenage winger David Scott returned to his home city to help Scotland beat Ireland and launch the autumn European triangular series.
Scott was one of 10 debutants in the match in Glasgow, with the hosts fielding their youngest side ever.
The Scots' other tries came from Paddy Coupar, Josh Barlow and Alex Hurst, with Hurst and Scott kicking goals too.
Despite Liam Finn touching down for a try and kicking the goal, Ireland could not give new coach Mark Aston the win.
Both countries also play France as they continue their preparations for the 2013 World Cup.
Scotland coach Steve McCormack: "I'm delighted with the victory and the performance. The blend of debutants and younger players with our senior players was excellent.
"David Scott will get the headlines and rightly so with that performance - he has enormous potential.
"It's testament to the work put in with the development team and player pathway we have created."
