At the Second Spring Meeting, Assassin was third in a 200-guinea sweepstakes race to Dennis O'Kelly's horse Soldier and Mr. Davis' horse Plutus. Assassin forfeited a match race with the horse Cornwall (later called Boringdon) at the same meeting a few days later, and at the July meeting in Newmarket his owner paid 150 guineas to the owner of Young Eclipse (the 1781 Derby winner) for backing out of a match race.
