Finally, after players reach 50, U.S. Open champions earn automatic invites to three of the five senior majors: a five-year invitation to the U.S. Senior Open and a lifetime invitation to the Senior PGA Championship and Senior British Open. If they win those tournaments, their invitations become permanent. The other two senior majors are selected by the PGA of America's Board of Directors. One year after winning the U.S. Open, a player's invitation will be reviewed to make sure he or she has not exceeded a limit on consecutive years at any major and that no other player has been granted an exemption. Invitations are also given out for "merit" spots at the remaining four majors. In addition to the senior major titles, U.S. Open winners receive $1 million (with a cap of $10 million), which is the highest prize money award at any major, and a place in the history books as the only person to ever win the U.S. Open back-to-back. Winning the U.S. Open has many advantages because it is the only major championship that is open to men and women simultaneously. It is played on the same course each year so that the competition is always high, if not always higher than average.
