Despite a stellar record, Sifford was never invited to play in the Masters.
You know so little about the Masters, it has no color, no racial bounds, it is about rules to get invited and the rule is the top money earners in playing the game of golf get invited. Record doesn't count, it is playing certain events and earnings, that gets you the invite. Don't perform at the scheduled events you don't get invited. It's about golf performance, not race, not color, but pure performance through the year, that's why it is called the "MASTERS"
