In 1963, Nicklaus won two majors, so a fourth player was added to the World Series via an 18-hole playoff between the three men who had lost playoffs in that year's majors; Palmer and Jacky Cupit in the U.S. Open and Phil Rodgers in the Open Championship. Palmer prevailed by five strokes in the August playoff. Nicklaus repeated as the World Series winner in September, one stroke ahead of Julius Boros, with Palmer in third and Bob Charles in fourth. The opposite tour event in 1963 was the Utah Open in Salt Lake City, with a winner's share of $6,400.
