Ballydoyle's inmate turned in a very encouraging performance in the 2000 Guineas at Newmarket last weekend when chasing home Night Of Thunder and Kingman to take third place. Australia hardened as ante-post favourite for the premier Classic at Epsom, with his stout breeding giving every indication he will relish the step up to a mile and a half on June 7. O'Brien said: "He ran a blinder and obviously hasn't done much since. "We are very happy with him and hopefully we can get him to the Derby."
