Hall of Fame jockey Calvin Borel announced his retirement on Wednesday. He is reported to have said to a friend, “it is time.”

Borel won 5,146 races in a career that covered 33 years. The horses he rode earned more than $127 million. He is the only jockey to have won three Kentucky Derbies in four years. Known as “Bo-Rail” for his preference for riding the rail, Borel will be missed by racing fans.
