Baystone (1952−1978) was a racing horse and the winner of the 1958 Melbourne Cup[1] with jockeys Mel Schumacher,[2] J. Thompson, and F. Treen and trainers Jack Green,[3] F. Dalton and O.N. Marshall.[4] His winning time was 3:21:25 and his odds were ten to one. He finished the race one and a half lengths in front of the next racer, Monte Carlo.[5] Baystone was the first horse in Cup history winning with the number 7 saddlecloth.[6] The 1958 Melbourne Cup was the first one with automatic barrier stalls.[7]
Baystone was favored 10/1 partly due to the victory he claimed the Saturday before the race at the Hotham Handicap.[8]
