Eight Belles

Eight Belles (February 23, 2005 – May 3, 2008) was an American Thoroughbred racehorse who came second in the 2008 Kentucky Derby to the winner Big Brown. Her collapse just after the race resulted in immediate euthanasia. Earlier in the year, Eight Belles became the first filly in Oaklawn Park history to win the Martha Washington Stakes, the Honeybee Stakes, and the Fantasy Stakes. She won the Martha Washington by 13½ lengths, setting a stakes record for margin of victory.
