Repole in Derby chase with Outwork, son of top sire Uncle Mo

LEXINGTON, Ky. (AP) – Five years ago, Mike Repole was living the dream. He had already made his share of an estimated $4.1 billion fortune from the sale of the company that produced Vitaminwater, and now he had himself a Kentucky Derby favorite with a horse named Uncle Mo.

Repole would regale any and all about growing up in Queens, New York, near Aqueduct, heading the track after school, making bets and loving horses.

But Uncle Mo never made it to the Derby. A day before, he was withdrawn from the race because of what turned out to be a life-threatening liver ailment. The lightning-fast colt recovered, ran again and won, but was never the same. He was retired later in the year. Repole called Uncle Mo the best horse he’ll ever own.

And he wasn’t even talking about Uncle Mo’s life after racing. As a stallion, at stud in the breeding shed. With just his first crop of 3-year-olds, Uncle Mo already is a leading sire in North America – “red hot,” according to Coolmore Ashford Stud, where Uncle Mo is performing with mind-boggling success.

He’s the proud sire of three of the 20 3-year-olds running in Saturday’s Derby – from morning-line favorite Nyquist to long shot Mo Tom to a horse Repole owns, Wood Memorial winner Outwork. Tapit, a leading sire the past several years, also has three offspring in the Derby, but for a young sire like Uncle Mo to be so productive so early is rare.
