In golf, a Grand Slam is a very big deal. It means a player wins all four major games in one year. 
Today, the four major games are different. They are the Masters, the U.S. Open, the PGA, and The Open. 


Tiger Woods did something even more special. He held all four major titles at the same time. This is called the Tiger Slam. 

In the world of golf, a Grand Slam is a very special achievement. It happens when a player wins all the major championships in one single calendar year. 

To understand how it works, you have to look at the schedule. The Masters is held in April at the Augusta National Golf Club. 

The history of the Grand Slam started with a man named Bobby Jones. In 1930, he won four major championships that were different from the ones we see today.
Some players do not win all four in one year, but they win them over their whole lives. This is called a Career Grand Slam. Only six men have ever achieved this in the modern era. They are Gene Sarazen, Ben Hogan, Gary Player, Jack Nicklaus, Tiger Woods, and Rory McIlroy. 
Women's golf also has its own important major championships. While no woman has won all four in one calendar year, many have won a Career Grand Slam. Seven women have reached this goal, including Annika Sörenstam and Juli Inkster. One player, Karrie Webb, is even more unique. She is the only woman to win five different tournaments recognized as majors. This is known as a "Super Career Grand Slam." Just like the men, these women show incredible talent and dedication to their sport.
In the sport of golf, a Grand Slam represents the highest level of achievement. It is an unofficial term used to describe a player winning all major championships within a single calendar year. Because these tournaments are so difficult to win, achieving a Grand Slam is considered one of the greatest feats in sports history. 
To achieve a modern professional Grand Slam, a golfer must win four specific major tournaments. The cycle begins with the Masters Tournament, an invitational event held at the Augusta National Golf Club in April. 

There are different ways to categorize these massive achievements. A "Career Grand Slam" occurs when a player wins all the major tournaments at some point during their professional life, even if they are not in the same year. 
The history of the Grand Slam began with Bobby Jones in 1930. During that era, the major championships were different than they are now. Jones won the U.S. Open, The Open Championship, the U.S. Amateur, and The Amateur Championship. His success was so unexpected that the sports world struggled to name it. Writer O. B. Keeler eventually coined the term "Grand Slam" by borrowing a term from the game of bridge. Jones' victory was described as storming an "impregnable quadrilateral" of golf.
Professional players in the early 20th century had their own version of the Grand Slam. Players like Tommy Armour and Walter Hagen achieved a professional career Grand Slam in 1931. Their version included the two open majors, the PGA Championship, and three other major tournaments: the Canadian Open, the Western Open, and the Metropolitan Open. This shows how the definition of a "major" has shifted as the professional tour became more organized and global.
Only a very small group of men have ever reached the pinnacle of the modern game. Six golfers have accomplished a Career Grand Slam: Gene Sarazen, Ben Hogan, Gary Player, Jack Nicklaus, Tiger Woods, and Rory McIlroy. 
Women's golf also features a highly respected set of major championships. While no woman has completed a Grand Slam in a single calendar year, many have achieved a Career Grand Slam. Seven women have reached this milestone, including Annika Sörenstam and Juli Inkster. Karrie Webb holds a unique distinction in the sport. She is the only woman recognized with a "Super Career Grand Slam" because she won five different tournaments recognized as majors.
