Willie Mullins has a powerful five-strong entry in the Cathal Ryan Memorial Champion Novice Hurdle at Punchestown, headed by So Young, which was third to the Mouse Morris-trained First Lieutenant in the Neptune Investment Management Novices' Hurdle. Both horses are also engaged in the two-mile Evening Herald Champion Novice Hurdle.
