Robert A. "Bob" Baffert (born January 13, 1953 in Nogales, Arizona) is an American horse owner and trainer, whose horses have won three Kentucky Derbies, five Preakness Stakes, one Belmont Stakes and two Kentucky Oaks. He graduated from the University of Arizona's Race Track Industry Program with a Bachelor of Science degree.

Bob Baffert began his career as a jockey. As he grew bigger, he had difficulty maintaining the required jockey weight, (around 100-108 pounds), and he switched to the training of American Quarter Horses. In 1991, he began devoting himself to conditioning Thoroughbreds for flat racing. From a base in California, he became the United States' leading money-winning trainer four times. He got his first big break in 1992 when he won his first Breeder's Cup race with Thirty Slews.

Nicholas Philip "Nick" Zito (born February 6, 1948 in New York City, New York) is an American Thoroughbred horse trainer.

Zito began his career as a hot walker and worked his way up to a groom, to an assistant trainer, and to a trainer. His first top level horse was Thirty Six Red with which he won the 1990 Grade 1 Wood Memorial Stakes and earned a second place finish in that year's Belmont Stakes. Nick Zito went on to win the Preakness once, and the Kentucky Derby and Belmont Stakes twice. He got his big break in 1991 when he won his first Kentucky Derby on Strike The Gold.

He was inducted into the National Museum of Racing and Hall of Fame in 2005, a year that his stable won more than $8 million in purses. Zito has also trained the 1996 U.S. Champion2-Year-Old Filly Storm Song as well as Bird Town who was voted the 2003 U.S. Champion 3-Year-Old Filly.
