has anyone won the open back to back
The reigning champion of the competition is automatically invited to play in the other three majors (Masters, the U.S. Open, and the PGA Championship) for the next five years. The prize of the tournament is the Golf Champion Trophy, commonly known as the Claret Jug, and the champion personally keeps the trophy until the next competition the following year. The champion also receives a gold medal, which they are allowed to keep permanently. Until 1870 the champion received the Challenge Belt, however when Tom Morris Jr. (more commonly known as Young Tom Morris) won the Open Championship three times in a row he won the belt outright, necessitating the need for a new trophy.
