Limerick hit six
Jeff Judge blasted home superbly from 25 yards on 19 minutes and added an equally impressive second nine minutes later with a low 20-yard drive. Paudie Quinn trebled that advantage with a near-post header from a Shane Tracy cross.
Ten minutes after the break Karl Keogh deflected a Tracy flick-on from a Rory Gaffney corner into his own net while Denis Behan made it five with a 60th-minute penalty.
