Kilkenny see off Tipp
Kilkenny repeated their All-Ireland SHC final win over Tipperary with a 2-17 to 0-15 success in their NHL opener at Nowlan Park.
Richie Power tormented the Premier defence throughout, helping himself to a goal and 12 points.
Power's three-pointer helped the Cats to a 1-10 to 0-8 interval lead, and Eoin Larkin added a second goal in the second half.
Defending league champions Dublin made a losing start, going down by 0-20 to 0-13 at the hands of Galway at Pearse Stadium.
A handful of neat scores from Niall Burke helped the Tribesmen to a 0-9 to 0-8 half-time lead, and he went on to bring his total to 10 as the home side dominated after the restart.
Offaly defeated 14-man Laois by 1-27 to 0-18 at Tullamore. The Laois challenge faded after they had Michael McEvoy sent off on a second yellow card after 20 minutes.
James Mulrooney's early goal had already laid the foundation for an Offaly win, and they powered home thanks to the finishing of Joe Bergin and Shane Dooley.
Antrim proved too strong for Wexford at Casement Park, where they recorded a 3-18 to 2-15 win.
Eoin Quigley struck an early Wexford goal, but the Saffrons claimed three goals before the break, from Shane McNaughton, Kevin Sheerin and Karl Stewart, to take a 3-9 to 1-7 lead into the turnaround.
Quigley fired in his second goal, but McNaughton's 1-8 tally secured the spoils for Antrim.
