Osborn was always to the fore in the Vinegar Hill Maiden Hurdle and proved strongest in the closing stages at Wexford.
Niall Madden sent him on from the last to record a five-length victory for trainer Seamus Neville.
"He'll stay over hurdles for a bit but he's ultimately a chaser," said Neville.
"He could have another run in a winners hurdle and then go chasing. Three miles would be his trip as he won a point-to-point very handy. He's a good ground horse and we'll keep him going."
