O'Brien not worried by Master draw Aidan O'Brien doesn't think stall one will be a problem for Mastercraftsman in the Breeders' Cup Dirt Mile at Santa Anita on Saturday. The Irish 2000 Guineas and St James's Palace winner retained morning line favouritism following the post draw but is considered vulnerable by some. He said: "I don't think stall one will be a problem. Mastercraftsman's best ever run was over six furlongs and he wants a real hard, fast pace, which he should get in the Mile. "I hope that at half-way he's not too far back. I think they will go that fast that you're best saving ground than being drawn on the wide outside. "He's not used to racing over a mile at Polytrack pace but at Ascot, when we put loads of speed on, Johnny let him roll from halfway. "He'll probably come from halfway again and hopefully get there in time."
