We speak with jockey Tyler Gaffalione, who will ride Keeneland's Toyota Blue Grass winner Sierra Leone in Saturday''s 150th Kentucky Derby. Gaffalione was actually aboard Tampa Bay Derby winner Domestic Product when that colt worked with Sierra Leone this morning (April 27) at Churchill Downs, the pair clocked five-eighths in 1:00.1. "I'm living the dream right now," Gaffalione said. Video starts out with some b-roll. Sierra Leone and Domestic Product's splits were 13, 24.4, 36.2 and then out six furlongs in 1:13.1 and 1:26.1
