Davy Russell brought the Gordon Elliott-trained five-year-old to jump into the lead at the second-last flight, after Beyond The Law had made the running.
The 12-1 shot went on to score by 16 lengths from Burrows Saint, with Discorama two lengths further away in third.
Elliott said: "I said before the race, I couldn't believe what price he was and he's a nice horse."
Regarding being a contender for the Albert Bartlett at the Cheltenham Festival, he added: "There are plenty of races to be won in Ireland and we can't send them all to Cheltenham, but we'll see.
"He could be as he is a smart horse and wouldn't be out of place in a Graded race. I think a bit of him and coming here today the ground was actually a worry for him."
Elliott and owners Gigginstown House Stud were completing a quick double after Pete So High (7-1) landed the www.thurlesraces.ie Maiden Hurdle.
The four-year-old could be Cheltenham-bound after he strode away from two out under Jack Kennedy to score by five lengths from Last Man Standing.
"It wasn't the strongest race in the world and he just about handled the conditions. Jack said he wasn't in love with it, but whatever handles it best wins today," said Elliott.
"He has got his head in front now and we'll see, but he could be a Fred Winter-type horse."
