The Saints Under-18s produced another remarkable comeback, this time in Dublin, to go two from two in their pre-season preparations thanks to Fraser Dingwall's late, late penalty.
A converted try and penalty conceded saw them head for the changing rooms with a 10-0 deficit, but as they did against Wasps on Friday, the young Saints turned it up after the break.
Joe Green - among the scorers at Stowe School last week and the Singha Sevens before that - crossed twice to make it 10-apiece on the hour and when the opportunity for victory arose, Dingwall held his nerve.
