Orb powered through on the home stretch to win the 139th Kentucky Derby on Saturday, giving Hall of Fame trainer Shug McGaughey his first winner in the first leg of the Triple Crown.

Joel Rosario piloted Orb to the victory in the $2 million, 1 1/4-mile race on a muddy track at Churchill Downs, ahead of longshot Golden Soul and Revolutionary.

With the win, Orb gains a chance to become the first horse since Affirmed in 1978 to capture US flat racing's Triple Crown of the Kentucky Derby, Preakness and Belmont Stakes.
