Man O' Wars only loss as a two year old
In the early 1900s, there were no starting gates. Horses circled around and then lined up behind a piece of webbing known as the barrier and were sent away when it was raised. In Man o' War's only loss, the
Sanford Memorial Stakes,
he was still circling with his back to the starting line when the barrier was raised (though some accounts give other reasons). After Man o' War turned around, he already was far behind the starters. Jockey Johnny Loftus put Man o' War in a bad position, getting boxed in by other horses. Despite this, he came close to winning,
losing by a half-length. The winner was
Upset, whose name is sometimes erroneously thought to have popularized a new phrase in sports (meaning an underdog beating the favorite)—in fact, the term "upset" was already in use to describe such a situation decades before
Secretariat lost four times
OK you asked for it here they are >>
Every one of Secretariat's losses (5) can be attributed to unforeseen circumstances.
1. Secretariat came in 4th in his first race, because he got absolutely MUGGED at the start. He got knocked around by two other horses at the starting gate, and almost fell down. The race was only 5-1/2 furlongs, so Secretariat simply didn't have enough racetrack to make up the time he lost at the start.
2. Secretariat won the Champagne Stakes, but was disqualified to 2nd place because he (supposedly) bumped a horse too hard during the race. Turcotte stated that it was a ridiculous decision by the track stewards.
3. Secretariat lost the Wood Memorial (3rd place) due to a quarter-size abscess inside of his upper lip that bothered him greatly. Some of the Secretariat "handlers" (the grooms, exercise riders, and the track veterinarian) knew about the abscess, but Lucien Laurin, Penny Tweedy, and Ron Turcotte had no idea. The assistant trainer was notified about it, but never passed the word along to any of the three people who really needed to know. "Big Red" wasn't eating right, was in pain, and after treating the abscess with hot compresses for many days, it finally broke and healed shortly before the Kentucky Derby.
4. Secretariat lost the Whitney (2nd place) due to a low-grade fever that clearly bothered him. Ron Turcotte knew about the fever, told Lucien Laurin that he didn't think Secretariat should run in the race, but Laurin insisted that Secretariat run the race anyway.
5. Secretariat lost the Woodward (2nd place) because he had not been "properly" trained for the race (he was a replacement for Riva Ridge, who was supposed to run in the Woodward but the track was a muddy mess and Riva Ridge hated "off" tracks.
