Mr. Prospector showed early brilliance as a speedster on the racetrack, but nothing could have prepared the horse racing world for the spectacular progenitor he would become. By the time of his death at age 29 in 1999, Mr. Prospector had led the U.S. sire list twice (with his sons and daughters earning more than $16 million) and had led the broodmare sire list twice. He has since led the broodmare sire list seven more times. He sired 2000 Kentucky Derby winner Fusaichi Pegasus, who sold for $4 million as a yearling and was syndicated for stud duty for $70 million. Respected pedigree expert Avalyn Hunter looks at Mr. Prospector and his incredible impact on the American Thoroughbred.
