The final weekend of PwC Age-Grade Interprovincial Championship action kicked off in Belfast where the Ulster U-19s came out on top in a tight tussle with Connacht.
Charlie Reaney's rapid maul try after just 93 seconds set Ricky Andrew's side on their way, before Campbell College centre Paul Henry powered over on the quarter hour mark.
Connacht were hoping to bounce back to winning ways, with four points separating them from table-toppers Leinster coming into the decisive third round, but they were held scoreless during the first half.
A terrific turnover penalty won by Archie Graham helped Ulster to stay 14 points in front, until Sligo's Cathal Moffatt scored with a pick-and-go effort, early on the resumption.
It was all to play for entering the last quarter, as a yellow card for Graham was followed by a well-taken converted try from Connacht captain Ruben Flynn, who closed the gap to 14-12.
Boosted by a three-pointer from Josh McCaughey, Ulster showed impressive composure at a key stage. They used their maul again to very good effect for Ballyclare High School's Josh McColgan to touch down.
The conversion from McCaughey made it a double-scores lead and gave Andrew's youngsters enough of a cushion to see out their first victory, despite a late Tom Walsh try.
The Leinster U-19s, who have registered back-to-back bonus point wins, can retain the Barney McGonigle Trophy by beating Munster in Sunday's showdown at Energia Park (kick-off 5pm).
Coached by former Munster and Ireland back rower Tommy O'Donnell, the young Reds can still mathematically win the title, having beaten Ulster 41-21 to sit on six points.
