—Reds president Bill DeWitt, on why he traded Frank Robinson to the Orioles in 1966 Robinson won the Triple Crown that year and led Baltimore to a World Series title
That bold, risky move got just enough from his horse and at the finish, it was Affirmed by a nose to become horse racing’s eleventh and last Triple Crown winner.
That summer, Thrift Drugs, a major sponsor of American cycling, offered a one-million-dollar bonus to any rider who could win the Triple Crown of Cycling, which meant all three of the most prestigious races in the United States.
Racing ten times, Affirmed emerged triumphant on seven occasions, including three classic Triple Crown confrontations.
Perhaps no one on either team knew the answer as well as Graig Nettles, who had been with the Twins in 1967, when Yastrzemski, in that amazing Triple Crown season, had taken it upon himself to carry the Red Sox into the World Series.
Because the last jewel of the Triple Crown was the longest race—the 1-1/2-mile distance of the Belmont was a quarter of a mile longer than the Derby and 5/16 of a mile longer than the Preakness—most figured Alydar would finally vindicate his legacy with a win that would deny Affirmed the Triple Crown.
