Grand Slam (golf)
The Grand Slam in professional golf is winning all of golf's major championships in the same calendar year. The only player who has accomplished this feat is Bobby Jones in 1930, winning the four major tournaments of that era: the British Amateur, the British Open, the United States Open, and the United States Amateur.[1] Modern variations include a Career Grand Slam: winning all of the major tournaments within a player's career and the Tiger Slam: winning four consecutive major titles but not in the same calendar year (named after Tiger Woods, the only player to accomplish the feat).
This article is about the concept of winning all major golf championships in one year. For the golf tournament contested by the winners of the four men's major championships, see PGA Grand Slam of Golf.
