It meant the two sides once again shared the trophy, though having been denied the title by a late try in 2011, this time it was the Saints who came up with a final play score to leave the two sides deadlocked at 5-all.
The afternoon had begun with a tight victory for the youngsters in black, green and gold, a George Wacokecoke try and Sam Olver's penalty seeing off Scarlets 8-5.
Round 2 provided Welsh opposition once more and it was an altogether more comprehensive win over Ospreys, Onojaife and Alex Shorthouse the try scorers in a 17-0 win. The remaining seven points came from the boot of Harry Mallinder.
The next two games produced clean sheets too against the West Country's best. Steve Arroyo-Hover and last season's top try scorer Howard Packman registered as Gloucester were beaten 12-0, while it was Simon Uzokwe, Austin Beckett, Josh Skelcey and Packman once more who dotted down as Bath were swept aside 28-0. Mallinder contributed four more conversions across the two victories with Olver slotting one against Bath.
The squad of 29 players included no less than 14 Under-17s and Academy manager Alan Dickens was suitably impressed with the efforts of the entire squad.
"It was an excellent day," he said. "The most pleasing thing was how we got better and better as the tournament and the matches went on. The lads showed a good team spirit throughout and their attitude and commitment, particularly in defence against Saracens, also deserves a mention.
"There were some superb performances from the likes of Lewis Jones, Sam Harry, Reece Marshall, Jordan Onojaife and Josh Skelcey but the squad as a whole did well throughout and there were promising signs as we move forward."
The Saints Academy are in action again on Tuesday, August 28th when they welcome Ulster to Franklin's Gardens for a 2pm kick-off.
