While winning senior majors don't count toward a golfer's overall record, holding the mark for winning the most PGA Tour Champions major titles is still an accomplishment. In fact, it's an accomplishment that is particularly remarkable since a player has to have won all of their senior majors past the age of 50.
For most PGA Tour Champions players, that means a decade or so to win the majors they're going to get.
There are five senior majors recognized by PGA Tour Champions: the U.S. Senior Open, the Senior PGA Championship, the Senior Players Championship, the Senior British Open and the Regions Tradition (which began in 1989). The Senior British Open became a major in 2003.
