The impeccably-bred Ol' Man River lived up to his pedigree with a stylish victory on his debut Irish Stallion Farms EBF (C&G) Maiden at the Curragh.
Always travelling easily on the outside from his wide draw, the 11-10 favourite, trained by Aidan O'Brien, moved effortlessly to the lead in the final furlong of the one-mile contest.
Just pushed out by Joseph O'Brien, the son of Montjeu out of the Classic-winning mare Finsceal Beo barely had a race as he coasted home by three-quarters of a length from the staying-on Aared with Vilman third.
The winning trainer said of the youngster, who cost 2.85million euro as a yearling and has a host of lofty entries: "You'd have to be delighted with that first time. He's never been away and this was his first day on the track.
"It looked a good solid race and he travelled very strongly. He had to get tired going that gallop first time, but he cruised into the lead.
"We'll take our time with him and won't be in any panic. We'd rather go gentle and see what's going to happen.
"The good thing about him is he's a strong traveller and seems to have plenty of pace. Looking at today he wouldn't mind going back to seven furlongs.
"He was working with plenty of class and showing plenty of pace at home. You are always afraid first time what will happen and he was drawn in the car park.
"If we had a preference we'd rather go faster than softer, ground-wise."
Sky Bet introduced him at 20/1 in their 2015 Derby betting and spokesman Michael Shinners said: "Aidan O'Brien's two-year-old debutants nearly always improve on their first run so for this highly-touted son of Montjeu to win with a degree of comfort first time up was impressive.
"Obviously the Derby is a long way off and the market is flooded with the winner's stablemates, but he certainly looks a decent horse for the future on that performance."
