California Chrome made it look easy to win the world’s richest horse race, the $10 million Gr1 Dubai World Cup.
Last year’s runner-up, who went off as 15-8 joint favourite, dominated from a long way out and, once they turned for home, jockey Victor Espinoza’s mount moved clear.
The 2014 US Horse of the Year went on to triumph by four lengths, despite Espinoza’s saddle slipping back.
It is a first win in the race for Espinoza and trainer Art Sherman.
SA challenger Mubtaahij (16-1) took second for jockey Christophe Soumillon and trainer Mike de Kock, with Hoppertunity (25-1) third for trainer Bob Baffert.
It was a third win in three starts for California Chrome since injury ruled him out of a planned visit to Royal Ascot last summer.
