Master only precautionary entry Aidan O'Brien has declared Mastercraftsman as a precaution for Saturday's Queen Elizabeth II Stakes at Ascot. He will only run if stablemate Rip Van Winkle misses the Group One contest, meaning a field of four will go to post on Saturday. Delegator represents Godolphin while William Haggas' Prix du Moulin winner Aqlaam is the sole four-year-old in the line-up. The field is completed by Zacinto, runner-up behind Delegator in the Celebration Mile at Goodwood last time.
