This Day in History: 1948-05-1

H.A. “Jimmy” Jones, son of Ben A. Jones, stepped aside as the trainer of Citation, allowing his father to be named the colt’s official trainer in the Kentucky Derby. Ben Jones was attempting to match the record of H.J. Thompson, who had trained four Derby winners. Citation did win and Ben A. Jones subsequently won two additional derbies, in 1949 and 1952, to set the mark for most number of wins in the Run for the Roses, six. Jimmy Jones was named as Citation’s trainer in the Preakness and Belmont Stakes, however, giving the Jones family a Triple Crown sweep.
