Antrim fended off a spirited Limerick comeback to win 2-14 to 2-7 in their Division Three opener in Rathkeale.
Andy McEntee's side started superbly and held a six-point advantage at the break after Dominic McEnhill's penalty.
Limerick kept fighting and hit the back of the net twice in the second period.
However, Antrim weren't to be denied with Ruairi McCann scoring the Saffrons' second goal, before the visitors closed out the win by scoring four of the game's last five points.
Antrim were fast out of the blocks in Rathkeale, and looked comfortable when they raced into an eight- point lead following McEnhill's penalty.
However, Limerick rattled off 1-4 in a row either side of the break to cut the deficit to one, with Iain Corbett also finding the net from the spot.
Antrim appeared to have settled down with three straight points of their own in reply, but it was a one-point game once again when Tommy Childs scored Limerick's second goal of the contest.
But in a game where momentum swung back and forth, Antrim raced up the other end a minute later and McCann responded with a goal for the visitors.
That seemed to knock the wind out of Limerick's sails and the Saffrons scored four of the next five points after that to seal the win.
