Red Cadeaux ran a huge race in second but Animal Kingdom stamped his class on the Dubai World Cup to give America victory in the world's richest race at Meydan.

The 2011 Kentucky Derby hero was given a no-nonsense ride by Joel Rosario, who always had crack mare Royal Delta just in front of him as she set the early pace.

Making his move two-and-a-half furlongs out, Animal Kingdom showed a very smart turn of foot to effectively put the race to bed.

From the back of the pack, however, Ed Dunlop's Red Cadeaux rattled home along the far rail under Gerald Mosse, but while he was closing all the way to the line the prize was never going to be lost for the Graham Motion-trained winner.
