 This strategy worked through the first turn and into the backstretch as Secretariat and Sham led the field and then pulled away by a half-dozen lengths with Sham taking a brief lead at several points early in the race until Secretariat bolted ahead of him.The pair were possibly a dozen lengths ahead of the pack when Secretariat increased his pace and Sham fell behind sustaining a hairline fracture of his right-front cannon bone.Sham ultimately finished last as Secretariat pulled away to a win recorded at 31 lengths.
