Triple Crown Overview
The 2009 Kentucky Derby was the second-biggest upset in Derby history, and easily the biggest in modern times. The 50-1 longshot Mine That Bird rallied from 19th place to win the Derby by 6 ¾ lengths, also the second-longest margin of victory in Derby history. Only two horses in the field had longer odds than him, Atomic Rain at 55-1 and Join in the Dance at 51-1.
