Chaparral heads King George field Vodafone Derby winner High Chaparral headed Aidan O`Brien`s usual massive team when entries for the King George VI And Queen Elizabeth Diamond Stakes were revealed today.He is among no fewer than 17 Ballydoyle inmates put in the Ascot showpiece, exactly one third of an initial field reduced to 51 as Japanese star Jungle Pocket is a non-runner due to injury.Epsom runner-up Hawk Wing and Oaks second Quarter Moon are among others O`Brien has engaged in a race he won with Derby winner Galileo last year.Godolphin, successful in three of the past five runnings, have 13 horses in the July 27th contest, including last year`s Prix de l`Arc de Triomphe winner Sakhee and tomorrow`s Prince Of Wales`s Stakes hope Grandera.Asian Heights, High Pitched and Nayef are other high-quality British-based horses due to stake their King George claims at the Royal meeting this week.And the mile-and-a-half event could well live up to its billing as the summer middle-distance championship ofEurope if French Derby first and second Sulamani and Act One take up their entry, along with Germany`s Coronation Cup winner Boreal.
