Exogenesis swooped in the dying strides to snatch victory in the Korean Racing Authority Tyros Stakes at Leopardstown.
Ger Lyons' charge was sent off an 11-8 shot for the Group Three event after winning two of his three starts, including a race over this seven furlongs last time.
Gary Carroll had him handy throughout, sitting on the heels of the front-running Home School before switching out to challenge inside the final couple of furlongs, and though Home School battled all the way to the line, he had to concede defeat by half a length.
Lyons said: "He's what I thought he was and he's going the right way. It's not often we refuse good money for a horse and we were offered very good money for him after his last run, but we said no. If we're going where we want to go, we need to be brave with some of these horses.
"He's in the Group Two at Doncaster (Champagne Stakes) and I wouldn't want to go shorter than seven furlongs with him again.
"We're in no rush with him, we won't overdo him as I think he will make a nice three-year-old and he could be a horse for something like the Jersey Stakes.
"Everyday he runs, he's getting mentally better. Gary said the better the race, the better the horse."
