paragraph_text: In golf, winning all of the sport's major championships in the same calendar year constitutes the Grand Slam. The modern (professional) Grand Slam would mean winning The Open Championship, U.S. Open, PGA Championship and Masters Tournament in the same year. Before the rise of professional tournament golf, the Grand Slam was achieved in 1930 when Bobby Jones won the four major championships of that era: The Amateur Championship, The Open Championship, the United States Open, and the United States Amateur.
  
  Variations include a Career Grand Slam, which involves winning all of the major tournaments within a player's career. Six golfers have accomplished this: Gene Sarazen, Ben Hogan, Gary Player, Jack Nicklaus, Tiger Woods, and Rory McIlroy. Holding all four major titles at the same time has been done only once, by Woods in 2000–2001, and has become known as the Tiger Slam. A pre-Masters era professional career Grand Slam was achieved by Tommy Armour and Walter Hagen, in winning The Open, U.S. Open and PGA along with the next three biggest tournaments of the time.
