Limerick have won back to back All Ireland hurling titles for the first time in their history.
In front of 40 thousand fans, the defending champions dominated Cork at Croke Park.
First-half goals from Gearoid Hegarty, Aaron Gillane and Patrick Collins set them on their way.
The recalled Shane Kingston replied for the Rebels.
But it was the Treaty men's day and the final score at Headquarters was Limerick 3-32, Cork 1-22.
