Man of the match
Cathal Mannion (Galway)
A brilliant 3-3, including a hat-trick in ten minutes, Mannion effectively wrapped up the game before the first quarter had expired.
What happened to Dublin? Even wind-assisted they never raised a gallop as the tactic of leaving their full-back line with no cover early on was ruthlessly exposed.
Jason Flynn's overhead flick pass in the 17th minute to Aidan Harte for his point drew acclaim from all corners of O'Connor Park.
Brian Gavin let plenty go and kept the red card in his pocket despite flashing ten yellows in a testy enough game.
Galway 6 (5 in first half) Dublin 7 (2)
