Armagh all but secured a semi-final berth after easing past Antrim at Glenavy yesterday.
The Orchard men go into Wednesday's final group game against Monaghan in top spot with two wins from two and a massive 29 points scoring difference.
The game's first goal came from an Antrim error, keeper Colm Fleming's kick-out going straight to Ryan McShane, who lobbed to the net before a Jamie Clarke penalty two minutes later.
The game was as good as over when man of the match Stefan Campbell added a brace by the 19th minute and they were ahead 2-12 to 0-2 at the break.
Conaire Mackin was enjoying the opportunity to get forward and he added his second of the day just after the restart.
Patrick McBride tagged on three late points for Antrim, with Eoghan McCabe firing home a late consolation.
