Aminabad got off the mark over hurdles at the first time of asking when landing the Supporters Club AGM Maiden Hurdle at Wexford.
Willie Mullins' charge had won two out of four starts in bumpers and was always travelling smoothly under Ruby Walsh.
The even-money favourite took up the running at the last, and though Domesday Book kept on up the run-in, Walsh did not have to pull out all the stops on Aminabad to score by a length and a quarter.
Walsh said: "He jumped like a buck. I'd say two mile two is probably far enough for him. He will go back in trip rather than up I'd imagine. I got a great run through on him."
Mullins and Walsh completed a quick double when Measureofmydreams took the Slaney Maiden Hurdle.
Always to the fore, the 2/9 favourite took over from the pacesetting I Knew Well when that rival made a mistake at the last, and was driven home by Walsh to beat the front runner by six and a half lengths.
Walsh said: "He did it well but he is not a Wexford horse. He is more of a Navan or Naas horse, a big galloping track horse.
"Wexford is just tight enough for him and while he missed the last he picked up well."
