In another tight contest Sam Olver's right boot proved to be the difference, the fly half landing four penalties. Steve Arroyo-Hover scored the Saints' only try of the afternoon as the youngsters continued their recent good form that has included a win over Leinster Under-19s in Dublin and sharing the trophy at the recent Old Albanians tournament.
The Saints drew 5-5 with Saracens in the final that day, and there will be a rematch of this contest on Wednesday night at Franklin's Gardens. Kick off is at 7pm.
