[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).
The Grand Slam in men's golf is an unofficial term for winning all four major championships in the same year.
In the modern era, the Grand Slam requires victories in four tournaments in a single calendar year (listed in current playing order): Prior to the creation of the Masters Tournament, the national amateur championships of the U.S. and the UK were considered major championships.
George Trevor of the New York Sun wrote that Jones had "stormed the impregnable quadrilateral of golf."
Keeler would later write the words that would forever be linked to one of the greatest individual accomplishments in the history of sports:
[2] However, a newspaper article on 12 April 1960 titled "Biggest Grand Slam May Be Palmer Goal" stated "Arnold Palmer, the Midas of the fairways, has charted a course which could carry him to the biggest grand slam in golf since Bobby Jones' feat in 1930.
The Pennsylvania strongman with golfdom's golden touch passed his first landmark when he won the 24th Masters tournament yesterday with a pulsating stretch drive.
If the 29-year-old Palmer can add those three jewels to his Masters crown the performance will rank on a par with Jones' grand slam year.
"[3] Two years earlier, the PGA had changed to stroke play, and it started to be held two weeks after the Open Championship in 1960.
Tiger Woods came closest to winning a modern Grand Slam by holding all four major titles at the same time.
The seven are Pat Bradley, Juli Inkster, Inbee Park, Annika Sörenstam, Louise Suggs, Karrie Webb, and Mickey Wright.
However, because the U.S.-based PGA Tour Champions overwhelmingly dominates worldwide senior golf, its roster of majors is by far the most widely recognized.
Unlike the mainstream men's and women's (until 2013) Grand Slams, the senior version (as recognized by PGA Tour Champions) now contains five events.
Prior to the founding of The Tradition, Palmer and Player also completed that era's Career Senior Grand Slam.
