Ruffian.

About Ruffian

Ruffian was an American Thoroughbred racehorse who won ten consecutive races, including the Acorn, Mother Goose and Coaching Club American Oaks, then known as the American Triple Tiara. She was in the lead at every point of call in every race she ever ran and set new stakes records in each of the eight stakes races she won. Her dominating wins resulted in her being voted the American Champion filly at both ages two and three. In July 1975, she entered a highly anticipated match race with Kentucky Derby winner Foolish Pleasure, in which she broke down with two broken bones in her right foreleg. Surgery was attempted but Ruffian reacted poorly and exacerbated the injuries while coming out of anesthesia. As a result, she had to be euthanized.
