I'll Have Another cut loose down the home stretch to run down favorite Bodemeister and win the 138th Kentucky Derby on Saturday.
The winner, with a finish of 2:01:83, took in nearly $1.5 million of the $2.2 million purse.
Dullahan, with 12-1 odds, finished third.
In comments to NBC moments after the race, winning jockey Mario Gutierrez thanked all those involved in the effort as well as his family in Mexico and "my beautiful second family" in Canada, where he'd done most of his racing.
I'll Have Another had 15-1 odds; Bodemeister was at 4-1, according to the Derby website. Other favorites included Union Rags, Gemologist and Hansen.
A crowd of more than 165,000 revelers took in what's called either "the most exciting two minutes in sports" or "the fastest two minutes in sports."
The race is the first leg in the venerable Triple Crown; next up is the Preakness Stakes on May 19, followed by the Belmont Stakes on June 9.
Considered one of the sternest tests in thoroughbred racing, only 11 horses have ever won all three, the most recent being Affirmed, 34 years ago.
Nicknamed the "Run for the Roses" for the garland that is draped over the winner, the Kentucky Derby traces its rich history back to 1875, when Col. Meriwether Lewis Clark Jr. decided to inaugurate a race in his home state of Kentucky.Copyright © 2014, Los Angeles Times
