Man of the match
Cyril Donnellan (Galway)
A hat-trick from Donnellan marked him out as the game's outstanding performer. The centre-forward hit the net at crucial junctures when his side were struggling for traction.
John Shaw's equaliser with 12 minutes to go sparked Galway into life and they reeled off the next six scores to kill off the home side.
As John McIntyre acknowledged afterwards, Galway will have to make quantum leaps to compete with Dublin next time around, but they have only two weeks to do it.
After a minute's silence was observed for referee Anthony Stapleton's late father Jack before throw-in, the Laois official contributed to an entertaining evening. Was composed enough to consult both umpires and a linesman before awarding Shaw's disputed equalising score late on.

John McIntyre (Galway manager)

Brian Hanley (Westmeath manager)
"Your heart would go out to them, they didn't deserve to lose by so much."
