Before Bobby Jones, the term "Grand Slam" meant a home run with the bases loaded. In 1930, Atlanta sportswriter O. B. Keeler gave it a different meaning - winning the four biggest golf tournaments in the game. Since then it has come to be used in all individual sports to mean four wins in a single year or four consectutive wins.

The 1930 British Amatuer Open at the Old Course, St. Andrews, Scotland gave Bobby Jones his first shining moment. After defeating defending champ Cyril Tolley in the fourth round, Bobby came up against Roger Wethered, whom he beat 6 and 7 after being 6 up through the 13th hole

Two weeks later, at the British Open, the Royal Liverpool Golf Club, Hoylake, England, Jones captured his third title in four tries, beating Macdonald Smith and Leo Diegel by two strokes.

Following a parade in New York and Atlanta, Bobby returned to Interlachen Country Club, Minneapolis to best Macdonald Smith by two strokes in the U. S. Open.

By the time the U. S. Amatuer began at the Merion Cricket Club in Ardmore, PA, the world was watching Bobby Jones. Unknown to Bobby at the time, though, his first match would be his toughest, where he Sandy Sommerville, the Canadian Amateur champion. On the 29th hole of the final round, Eugene Homans conceded. Bobby Jones won the Grand Slam.
