Bruff face another final with Garryowen
Bruff, who lifted the trophy for the first time last season before going on to win the national Bateman Cup, laid the groundwork for the win with two first half tries when playing against the wind.
Shannon were rocked when Mike Carroll peeled off the back of a scrum to score a 22nd minute try and Cathal O’Regan heaped further misery on the hosts with a second try before the interval that Tony Cahill converted.
