The Senior PGA Championship is the oldest of the five major championships in men's senior golf. It is administered by the Professional Golfers' Association of America and is recognized as a major championship by both PGA Tour Champions and the European Senior Tour. It was formerly an unofficial money event on the European Senior Tour, but since 2007 has been an official money event.[1] Winners gain entry into the next PGA Championship. The winners prior to 1980, the first season of the senior tour, are not considered major champions of this event by the PGA Tour Champions.
The lower age limit is 50, which is the standard limit for men's senior professional golf tournaments. Like its PGA Tour counterpart, the Senior PGA Championship allows club professionals to enter. The tournament committee gives former winners of the PGA Professional National Championship a one time invitation upon turning 50 years of age and the top 35 club professionals who qualify through the Senior PGA Professional National Championship.
