Thunderello who was 22, was a fleet-footed sprinter who had three wins and three seconds out of seven lifetime starts that included a runner-up finish in the 2002 NAPA Breeders' Cup Sprint to Orientate at Arlington International Racecourse.

Trained by Scott Lake for all but his first start, Thunderello was second in his debut at 2 at Saratoga Race Course to Mayakovsky. Thunderello became a winner in his next start, winning by 14 1/4 lengths at Saratoga and finishing only a quarter of a second off Mayakovsky's record.
The colt was a close second in his debut at 3 and followed with two wins by a combined 5 1/2 lengths, which included a victory in the Gallant Bob Handicap. He went on to the Breeders' Cup, where he led the field through blistering early fractions of :21.53 and :43.91.
