Under bright blue skies, American Pharoah was favorite in a star-studded field for the 141st running of the prestigious race.

In a thrilling finale, the two-year-old bay colt edged out Firing Line at the winning post.

It marked a second straight win at the Derby for jockey Victor Espinoza, victorious on board California Chrome a year ago.

Last year California Chrome won the Preakness Stakes, but the horse's bid to win the Triple Crown came unstuck in the Belmont Stakes.

It is not quite the same rags-to-riches glory story for this year's winner, owned by multimillionaire businessman Ahmed Zayat.

It proved an emotional race for Zayat and his family -- the horse's owner was sprayed with champagne by jockey Espinoza in the ensuing celebrations.

Zayat made his money predominantly from selling his Egyptian brewing business to Heineken for an estimated $280 million.

Espinoza will once more be on board for Saturday's Preakness Stakes, part two of his latest attempt to win horse racing's Triple Crown.

The Preakness Stakes is held at Pimlico Race Course in Baltimore, Maryland.

No doubt, many hats, in all shapes and sizes will be out in force at Pimlico on May 16.

Saturday's race will be the 140th running of the Preakness, which has a prize purse of $1.5 million.
