Auld Enemy put up a promising display when making all the running to make a winning debut in the Requinto EBF Maiden at Navan.
David Wachman's son of Fastnet Rock (13-2) broke away smartly under Wayne Lordan to grab the far rail and dictate affairs.
Well in command, the juvenile went on to score by a length and a half from Black Beach, with the always prominent favourite Stone Mountain third.
The trainer said: "He's a grand colt. He had a good draw and was reasonably professional. He wants further and we'll get him home and make a plan for him then."
Wachman and Lordan completed a double when Curvy followed up last month's course and distance success in the Irish Stallion Farms EBF Fillies Handicap.
It was a close-run thing, as Dragon Fei collared Jeremy's Girl close home only to be caught by the 15-8 favourite in the shadow of the post.
"She's a nice filly. She'll run in stakes races now. She's got a good pedigree so it's important to get some black type," said Wachman.
