What was expected to be another runaway win turned into quite a surprise for the fans at Aqueduct on April 21, 1973. Secretariat's stablemate, Angle Light, wired the field to take the Wood Memorial, New York's final key prep on the way to the Kentucky Derby. Challenger Sham was second, while Secretariat hung to finish third. It was later revealed that Secretariat had an abscess in his mouth that likely bothered him. However, the performance planted seeds of doubt that perhaps Secretariat didn't want to run at the classic distances.
