Arrogate put on a show to win the world's richest race as California Chrome's career ended in disappointing fashion at Gulfstream Park.
Odds-on favourite Arrogate demonstrated why he ended last year as the top-rated horse on the planet, charging to victory in the inaugural Pegasus World Cup in Florida.
The Bob Baffert-trained favourite surged away under Mike Smith to pick up the $7million prize money, with the great California Chrome heading to stud on the back of almost being pulled up in his final race.
Shaman Ghost came home in second, with Neolithic back in third as Arrogate was in a class of his own and California Chrome could only finish back in ninth.
"I say this with all due respect to the other horses - he got to gear down for the last good hundred yards," said winning jockey Smith.
"He's got some turn of foot and some stride."
California Chrome's trainer Art Sherman said of the retiring six-year-old: "He looked like he was listless, I don't know why. It's the first bad race he's ever run.
"We've had a great run. I congratulate Bob Baffert, that horse really is a super nice horse and I can't say enough about him. We'll see, he's going to the breeding shed and I'm hoping his babies come back to me.
"It's been one hell of a journey for me."
