Aidan O'Brien's colt, who is a full-brother to classy stablemate Highland Reel, was played late by Joseph O'Brien as Theodorico and market leader Munaashid threw down their challenges.
However, the 4-1 victor picked up really well when asked to stretch and was soon into top gear, cutting down his rivals with a withering run before putting three and a half lengths between himself and eventual runner-up Theodorico.
Raymonda (4-1) was another youngster to create a favourable impression when she made a winning debut in the opening Irish Stallion Farms EBF Fillies Maiden and looks a smart prospect for Dermot Weld and Pat Smullen to go to war with next term.
She easily outpointed Twin Falls by two and three quarter lengths while Smullen completed a quickfire double when Oliveraie (8-1) claimed top honours in the Curragh 2016 Starts 20th March Handicap, but only after a stewards' inquiry.
