Main Sequence (foaled 13 February 2009) is a Kentucky-bred Thoroughbred racehorse. In his first three seasons he raced in Europe winning his first four races including the Lingfield Derby Trial before losing his unbeaten record when finishing second in the 2012 Epsom Derby. After failing to win in 2013 he was gelded and sent to race in the United States. In 2014 he recorded Grade I victories in his first four American starts, winning the United Nations Stakes, Sword Dancer Invitational Handicap, Joe Hirsch Turf Classic Invitational Stakes and Breeders' Cup Turf. He extended his winning run in his first start of 2015 but was retired from racing after suffering a serious tendon injury in his third race of the season.
