Hale S. Irwin (born June 3, 1945) is an American professional golfer. He is one of the few players in history to have won three U.S. Opens and was one of the world's leading golfers for much of the 1970s and 1980s. He has also developed a career as a golf course architect.

Irwin was born in Joplin, Missouri, but was raised in Baxter Springs, Kansas. He graduated from the University of Colorado at Boulder in 1967, where he was a two-time All-Big Eight defensive back, as well as an academic All-American in football. He won the individual NCAA Division I Championship in golf in 1967 and turned professional the following year.

Irwin had 20 victories on the PGA Tour beginning with the 1971 Sea Pines Heritage Classic and finishing with the 1994 MCI Heritage Golf Classic, and won prize money of just under six million dollars. His 1994 Heritage win at the age of nearly 49 made him one of the oldest winners in Tour history. He also won two Piccadilly World Match Play Championships at Wentworth in the 1970s. His successes kept him ranked high among his peers - he was ranked among the top five in McCormack's World Golf Rankings in every year from 1975 to 1979, inclusive. He ranked in the top-10 of the Official World Golf Rankings for a few weeks in 1991.

Bernhard Langer (born 27 August 1957) is a German professional golfer. He is a two-time Masters champion, and was one of the world's leading golfers throughout the 1980s and 90s, being the first official number one ranked player in 1986. After turning fifty, he became one of the most successful players on the Champions Tour.

Langer was born in Anhausen near Augsburg, Bavaria, Germany. He turned professional in 1976 and has won many events in Europe and the United States, among them The Masters in 1985 and 1993. He was the inaugural World Number 1 when the Official World Golf Rankings were introduced in 1986. He was elected to the World Golf Hall of Fame in 2001 (but deferred his induction until 2002). He ranks second in career wins on the European Tour, with forty and has also played regularly on the U.S. based PGA Tour, especially in the late 1980s and since 2000. He has shown great durability, finishing in a tie for fifth at The Open Championship the month before his forty-eighth birthday and regaining a place in the top hundred of the rankings three months before his fiftieth birthday. He is one of the game's most successful globetrotters, being one of only a handful of players to have won sanctioned professional tournaments on every continent on which the game is played: Europe, Asia, North and South America, Africa and Australia. He played on 10 Ryder Cup teams (1981, 1983, 1985, 1987, 1989, 1991, 1993, 1995, 1997, 2002) and was non-playing captain of the victorious European team in 2004.

David Knapp Stockton (born November 2, 1941) is an American professional golfer who has won tournaments on both the PGA Tour and the Champions Tour.

Stockton was born in San Bernardino, California. He attended the University of Southern California and turned professional in 1964. His first PGA Tour win came at the 1967 Colonial National Invitation. He was selected by former Colonial champions as one of two Champion's Choice invitations; he is the only Champion's Choice invitee to win the Colonial in the year of the invitation. His best year was 1974, when he won three times, but his two majors, both of which were PGA Championships, came in 1970 and 1976. In 1970 he played the final round with Arnold Palmer, shooting an erratic seventy-three which included an eagle and a double-bogey on the seventh and the eighth holes, and making a bogey on the thirteenth despite putting a ball in the water. In the end, this effort was good enough for a two stroke victory over Palmer and Bob Murphy. Due to rain at the 1976 PGA Championship, which was held at the Congressional Country Club, the final round had to be delayed until Monday. Stockton sank a fifteen-foot par putt at the seventy-second hole to avoid a three-man playoff with Raymond Floyd and Don January.
