Don't Touch It made it third time lucky over jumps after two second places with a smooth victory in the Donohue Marquess Maiden Hurdle at Leopardstown.
The race developed into a two-horse affair from the outset with Beau Mome leading from Don't Touch It (8-11 favourite).
Barry Geraghty was always happy on the latter and cruised into the lead after the second-last flight.
Don't touch It, trained by Jessica Harrington, pulled clear with the minimum of fuss to score by 13 lengths from Beau Mome, who just held Lip Service for second in a race few got involved in.
Harrington said: "Ruby (Walsh, on Beau Mome) put it up to him, and he put it to bed fairly quickly into the straight. He fiddled the third-last but apart from that he jumped well. He quickened away well.
"I'm not sure what the plan will be, but I think he could be very good. He has a lot of gears and he's been learning all the time."
