Seabiscuit?

A tiny, scrappy, 51-1 long shot ran away from the field to win the “Run for the Roses” yesterday, giving its eclectic jockey and everyman trainer the second-biggest upset in Kentucky Derby history.

Mine That Bird, purchased for a measly $9,500, came from the back of the pack to leave dozens of million dollar horses in his wake – immediately evoking memories of Seabiscuit, the tiny horse with the big heart whose string of improbable victories inspired America during the Great Depression.

Weaving through traffic before making their final dash down the rail, Bird and jockey Calvin Borel simply overpowered the field.

Borel – who won his second Derby – was overcome with emotion after the win.

So was the crowd.

Mine That Bird received an ovation not seen at Churchill Downs in decades, a fitting tribute to what some analysts are already referring to as the greatest upset in horse racing history.

Technically, Donerail in 1913 was the biggest Derby upset, but it’s doubtful anybody beneath the Twin Spires on Saturday remembered that race.

Meanwhile, first-time Derby trainer Bennie Woolley Jr. hobbled on crutches to the winner’s circle, another in a cast of improbables.

“They’ll know me now,” the man behind the dark glasses and handlebar moustache told NBC following his horse’s dramatic upset.

Indeed, no trainer has ever arrived at Churchill Downs with less acclaim – and left with more fanfare – than Woolley.

In fact, in a tale you’ll probably see recreated for the Silver Screen before too long, Woolley drove his own horse all the way across the country in a wagon hitched to back of a pick-up truck.

Amazing … congrats to all, and we look forward to watching Mine That Bird in the Preakness Stakes on May 16.
