The winner receives invitations to three of the major championships, namely the following month's Open Championship, and the following year's Masters Tournament and U.S. Open provided he remain an amateur prior to each major. The Amateur Championship is open to amateur golfers of any nationality in good standing with their national federations. Briton John Ball won the most career titles, with eight. Ball was still competing in the event as late as 1921 at Royal Liverpool Golf Club. In modern times, Briton Michael Bonallack's five titles lead. The most famous American winner of the competition was Bobby Jones, whose 1930 victory was part of his Grand Slam.
