Invitational: These events are similar to the regular ones, but have a slightly smaller field and do not follow the normal PGA Tour exemption categories. Invitational tournaments include the Charles Schwab Challenge, the Arnold Palmer Invitational, the RBC Heritage, the Memorial Tournament. The tournaments usually have an association with a golf legend, or in the case of the RBC Heritage, a famous course. The table below illustrates some of the notable features of the exemption categories for these events:
Similar to other major league sports, there is no rule that limits PGA Tour players to "men only". In 1938, Babe Zaharias became the first woman to compete in a PGA Tour event. In 1945, Zaharias became the first and only woman to make a cut in a PGA Tour event. In 2003, Annika Sörenstam and Suzy Whaley played in PGA Tour events, and Michelle Wie did so in each year from 2004 through 2008. In 2011, Isabelle Beisiegel became the first woman to earn a Tour card on a "men's" professional golf tour, the Canadian Tour, now PGA Tour Canada.
Before the transition, the Tour held a group of events known as the PGA Tour Fall Series, which provided a final opportunity for golfers to make the top 125 in season earnings and thereby retain their Tour cards. With the change to an October-to-September season, several of the former Fall Series events will now open the season. The Tour also sanctions two events in Asia during that part of the year:
The tour began 91 years ago in 1929 and at various times the tournament players had attempted to operate independently from the club professionals. With an increase of revenue in the late 1960s due to expanded television coverage, a dispute arose between the touring professionals and the PGA of America on how to distribute the windfall. The tour players wanted larger purses, where the PGA desired the money to go to the general fund to help grow the game at the local level. Following the final major in July 1968 at the PGA Championship, several leading tour pros voiced their dissatisfaction with the venue and the abundance of club pros in the field. The increased friction resulted in a new entity in August, what would eventually become the PGA Tour. Tournament players formed their own organization, American Professional Golfers, Inc. (APG), independent of the PGA of America. Its headquarters were in New York City.
