Mt Leinster made all in the qualified riders' race in Listowel to post a decisive victory.
The 9/4 favourite travelled well for Patrick Mullins racing to the home bend and had closest pursuer Cape Gentleman beaten off coming to the final furlong.
He came in by five lengths from the aforementioned Cape Gentleman who attracted support from 33/1 down to 18/1 on the off. Arcadian Sunrise was another eight and a half lengths back in third at 5/2.
Willie Mullins said: "It was a good performance and we said we'd change tactics with him and let him rock and roll and see if it works. It mightn't work again but it worked for today anyway.
"We'll be pursuing a chasing career now; I have him entered at Punchestown on Tuesday but he won't run there. I saw today's race and entered him and we said we'd take our chance and we'll hopefully go chasing now."
This was the fourth victory of Mt Leinster's career.
