LOUISVILLE, Ky. — A little known jockey and a lightly regarded horse pulled off an upset victory for trainer Doug O’Neill at last year’s Kentucky Derby.

On Saturday, he’ll give another relative unknown a chance of not only winning the big race but joining him in the record books if that happens. Kevin Krigger, the first black jockey in the Derby since 2000, will be aboard O’Neill’s Goldencents, considered a much stronger contender than last year’s winner, I’ll Have Another.

Only six trainers have won consecutive Derbies in 138 years, and no black jockey has won since 1902. The 29-year-old Krigger hails from St. Croix, Virgin Islands, and had some success on the smaller Northern California circuit before trying his luck in the big leagues of Los Angeles.
