Mayo lower Kingdom colours in Killarney while Rebels edge past Dublin
Cork 1-15 Dublin 0-16 ; Kerry 0-10 Mayo 2-11
Mayo inflicted a seven-point defeat on All-Ireland champions Kerry while Cork opened their National League campaign with a narrow win over Dublin.
Eamon Fitzmaurice's side were second best for most of the encounter which was held up early in the first half with a nasty looking injury to corner forward Evan Regan.
On Leeside, the Rebels will have gone some way to avenge last year's painful league semi-final defeat to the Dubs when they emerged victorious in what was a close contest throughout.
Jim Gavin's side made the early running and picked off the first two scores of the game before Fintan Goold and John O'Rourke brought the sides level.
The first goal came from an unlikely source when Rebel defender Jamie O'Sullivan found the net which sparked Jim Gavin's side into an immediate response.
The 2013 All-Ireland champions reeled off four successive points before Colm O'Neill, who was becoming a more influential figure in Pairc Ui Rinn, levelled the sides.
In what was a scrappy first half, Dean Rock helped himself to four points as the Dubs trailed 1-07 to 0-09.
The first three points after the interval went the way of the boys in blue and the second half was a real nip-and-tuck affair with O'Neill, Kevin McManaman and Brian Hurley featuring strongly.
However it was the home side that finished the stronger with Eoin Cadogan and Cian Dorman, a late call-up before throw-in, getting the final scores of the game as Brian Cuthbert's side edged the encounter 1-15 to 0-16 in front of 4,245 spectators on Leeside.
Barry John Keane and Evan Regan swapped points before the game was held up for more than five minutes after the Mayo corner forward received treatment after falling awkwardly on the ground.
Paul Geaney hit a lovely score to give the hosts a two-point cushion but Alan Freeman struck for Mayo to quieten the home crowd.
Substitute Michael Conroy made a quick impression and had three points to his name, while Donal Vaughan and Jason Doherty added further scores as Mayo led at the interval 1-07 to 0-04.
Tommy Walsh made his return to competitive action for the Kingdom and they began to make inroads into the deficit with Michael Geaney, Barry John Keane and a 45 from David Moran bringing it back to a three-point game before Mayo effectively sealed the game with their second goal of the game.
Wing-forward Kevin McLoughlin found the top corner of the net to put daylight between the sides, a gap which ultimately the All-Ireland champions could not bridge as the Noel Connolly and Pat Holmes saw their side run out 2-11 to 0-10 winners.
In Division Two there were wins for Galway, Down and Westmeath while Roscommon and Cavan ended in a draw.
In the Walsh Cup Dublin and Galway will meet in the final after wins today over Laois and Carlow respectively. Both teams hit 2-18 to set up the final most had predicted.
