Rich Strike, the long shot horse that was not expected to run in Saturday’s biggest race, pulled off a shocking victory at the 148th running of the Kentucky Derby.

The No. 21 horse, who had 80-1 odds entering the race, was the first alternate. He was added to the race after Ethereal Road was scratched from the lineup Friday morning. The race marked jockey Sonny Leon’s first time winning the Derby. With his odds, Rich Strike was the longest shot on the board, making his victory a historic upset.
