Majestic Prince
To this day, speculation abounds as to why McMahon changed his mind and raced Majestic Prince in the Belmont, but the pressure from the press was intense, including Whitney Tower's article in "Sports Illustrated" entitled "The Prince Ducks the Big One". The decision to run never sat well with Longden, and despite his well-documented shouting match with the horse's owner in the days leading up to the race, Majestic Prince was still sent out to compete in the Belmont Stakes. The first horse in history to enter the race undefeated, having won the Derby and the Preakness, finished second, beaten by Arts and Letters by 5½ lengths. Majestic Prince never raced again. This feat was later matched by Smarty Jones in 2004.
