- Grand Slam
- The Modern (or Professional) Grand Slam describes winning the four professional Major Championships -- the PGA Championship, the Masters and the United States and British Opens - in a calendar year. The Career Grand Slam describes winning each of these events once in a career. No one has ever won the Modern Grand Slam. The PGA of America's Grand Slam of Golf is a late-season event that features the winners of that year's four Professional Major championships.
