Early Doors claimed his second victory in the space of a fortnight with a smart display in the Fishery Lane Hurdle at Naas.
Joseph O'Brien's four-year-old made a big impression on his debut at Punchestown before finishing third in the Goffs Land Rover Bumper in April.
He justified odds-on favouritism on his hurdling debut at Wexford in late October and was a 3-1 shot stepped up to Grade Three level.
Early Doors travelled well into the home straight and while 5-4 favourite Meri Devie would have made more of a race of it but for encountering traffic problems, O'Brien's charge passed the post two lengths to the good, providing owner JP McManus and jockey Mark Walsh with the middle leg of a treble.
The pair also combined successfully on the card with Red Jack and Oscar Knight.
McManus' racing manager Frank Berry said: "He ground it out well.
"Mark liked him at Wexford. He was a bit green there and he thought he'd improve, which he has. He jumped a bit novicey early but he got the hang of it well. You would have to be pleased with him.
"It was nice to get today out of the way and we'll see where we go now. He handled the ground quite well and hopefully will go on from there."
