The golf Grand Slam refers to winning all four major championships in men's
professional golf. There are two main types: 1. Calendar-Year Grand Slam:
Winning all four major tournaments in the same calendar year. The four majors
are:
- The Masters Tournament
- PGA Championship
- U.S. Open
- The Open Championship (British Open)
This feat has never been accomplished in the modern professional era. The only player to achieve a version of the Grand Slam was Bobby Jones in 1930, but his majors included the U.S. Amateur and British Amateur instead of the Masters and PGA Championship, which did not yet exist in their current form
. 2. Career Grand Slam:
Winning each of the four majors at least once over the course of a golfer's
career. This is more common but still very rare. Only six men have achieved
this in the modern era:
- Gene Sarazen
- Ben Hogan
- Gary Player
- Jack Nicklaus
- Tiger Woods
- Rory McIlroy (completed in 2025)
Tiger Woods also held all four major titles simultaneously across two seasons (2000–2001), a feat known as the "Tiger Slam," but not within a single calendar year
. In summary, the Grand Slam in golf is the prestigious achievement of winning all four major championships, either in a single year (calendar Grand Slam) or over a career (career Grand Slam)
