Secretariat (horse) [SEP] Background
Chenery later said that both owners hoped they would lose the coin toss, which was held in the fall of 1969 in the office of New York Racing Association Chairman Alfred G. Vanderbilt II, with Arthur "Bull" Hancock of Claiborne Farm as witness. Ogden Phipps won the toss and took the 1969 weanling filly out of Somethingroyal. The filly was named The Bride and never won a race, though she did later become a stakes producer. Chenery received the Hasty Matelda colt in 1969 and the as-yet-unborn 1970 foal of Somethingroyal, which turned out to be Secretariat.
