The classy Zubayr made a winning debut over hurdles for the yard when successful at Southwell under Byrony Frost.
He has some classy back form over timber on his card, including a runner-up finish in a Scottish Champion Hurdle.
He warmed up for this return to jumping with a run in the big charity flat race at York earlier in the month.
Given a great ride by Bryony, Zubayr pinged the last and stayed on strongly to win by a length and three quarters.
