L'Impresario put up a promising performance when making a winning debut in the Boylesports 143 Shops Nationwide Maiden at the Curragh.
The Jim Bolger-trained half-brother to Antonius Pius had plenty to do when Eytarna kicked for home early in the straight. However, he quickened nicely for Kevin Manning and the 6-1 shot pulled clear in the final 100 yards to score by two lengths.
Eytarna just held the odds-on Changingoftheguard for second place.
Bolger said: "He's a good horse and when they come from behind like that, they have a bit of class.
"He'll go down the Listed route now and ideally for a winners of one race as he looked green.
"He came to me last year but he was a big horse and needed time."
Alshahbaa (7-2) looked good as she made a successful racecourse bow in the boylecasino.com European Breeders Fund Maiden.
Declan McDonogh brought the Kevin Prendergast-trained filly with a smooth run to lead just over a furlong out.
She ran away from her rivals to win by four lengths from Grace And Virtue with Macnas third.
Prendergast said: "I thought Alshahbaa would run well but didn't expect her to win so far!
"I've no plans for her yet, but being by Alhaarth she would probably like a dig in the ground."
Johnny Murtagh followed up his victory on Again in the Irish 1000 Guineas by completing a quick double on Sesenta in the Boylesports Best Price Guaranteed Handicap.
The in-form jockey was at his strongest on the 2-1 favourite as he got Willie Mullins' charge home from Speed Ticket by a head.
