Understanding Grand Slams
Calendar Year Grand Slam: Winning all four majors in a single calendar year (only 4 players have done this: Budge 1938, Laver 1962 & 1969, Court 1970, Graf 1988).
Career Grand Slam: Winning all four majors at any point during a player's career (12 players as of 2026).
When people ask if any tennis player has won all four majors, they're usually referring to the Grand Slam in tennis. But the answer isn't as simple as yes or no. The term "Grand Slam" has two distinct meanings in tennis, and understanding the difference is key to answering this question correctly. Let's break it down.
What Are the Four Grand Slam Tournaments?
The four Grand Slam tournaments in tennis are the Australian Open, French Open, Wimbledon, and US Open. Each is held annually and represents the pinnacle of the sport. Here's what makes each unique:
- Australian Open - January on hard courts in Melbourne
- French Open - Late May to early June on clay courts in Paris
- Wimbledon - June and July on grass courts in London
- US Open - August and September on hard courts in New York
Winning any one of these tournaments is a career-defining achievement. But winning all four? That's where things get complicated.
Calendar Year Grand Slam: The Rare Feat
Only four players have ever won all four Grand Slam tournaments in a single calendar year. Don Budge accomplished this in 1938, becoming the first player to achieve the feat. Rod Laver did it twice-in 1962 and 1969. Margaret Court completed her calendar year Grand Slam in 1970, making her the only woman to achieve this until Steffi Graf did it in 1988. Graf won the Australian Open in December 1987 (which counted toward the 1988 calendar year), followed by the French Open, Wimbledon, and US Open in 1988. Since Graf's 1988 victory, no player has managed to win all four tournaments in a single year.
The difficulty of winning all four in one year comes from the varying surfaces-hard, clay, grass-and the physical and mental demands of competing at the highest level across different continents within a short timeframe. Modern tennis has more depth than ever, with top players specializing in certain surfaces. For example, Rafael Nadal dominates clay but struggles on grass, while Novak Djokovic excels on hard courts and grass but faces tough competition at the French Open.
Career Grand Slam: Winning All Four Over Time
A Career Grand Slam means winning each of the four Grand Slam tournaments at least once during a player's career, but not necessarily in the same year. Many legendary players have achieved this. Don Budge and Rod Laver did it during their careers, but they also won the calendar year Grand Slam. Other players include Roy Emerson, Andre Agassi, Rafael Nadal, Roger Federer, Novak Djokovic, Serena Williams, Steffi Graf, and Margaret Court.
- Nadal completed his Career Grand Slam after winning Wimbledon in 2010
- Federer achieved it with his 2009 French Open victory
- Djokovic completed his Career Grand Slam at the 2022 Australian Open
- Serena Williams won all four majors at different points in her career, with her last Grand Slam title coming at the 2017 Australian Open
This feat is still incredibly difficult but more achievable than the calendar year Grand Slam because players can spread the wins across multiple seasons. As of 2026, 12 players have achieved a Career Grand Slam-7 men and 5 women.
Why Winning All Four in a Single Year Is So Hard
Winning all four Grand Slams in one year is one of the hardest achievements in sports. The reasons are clear. First, the surfaces vary drastically-hard courts, clay, grass-each requiring different skills and strategies. Second, the tournaments are spread across the globe, with players needing to travel between continents in a short time. Third, the physical toll of competing in four major tournaments within a few months is immense. Fourth, the competition is fierce. Modern tennis has more depth than ever, with top players specializing in certain surfaces.
For example, Rafael Nadal is dominant on clay but less so on grass or hard courts. Novak Djokovic excels on hard courts and grass but struggles at the French Open at times. The Australian Open is often overlooked by top players, but it's still a tough tournament with intense heat and pressure. No current player has the versatility to dominate all four surfaces in a single year. The last time it happened was 1988, and since then, the sport has become more competitive and specialized.
Common Misconceptions About Grand Slams
Many people confuse the terms "Grand Slam" and "Career Grand Slam." Some think that winning all four majors at any point means a Grand Slam, but technically, that's a Career Grand Slam. The true Grand Slam is winning all four in one year. Another misconception is that the term "Grand Slam" applies to any tournament win. In reality, it specifically refers to the four majors.
Some fans also believe that players like Rafael Nadal or Novak Djokovic have won a Grand Slam in a single year, but neither has. Djokovic came close in 2015 and 2023, winning three majors but missing the French Open. Nadal's 2010 season saw him win the French Open and Wimbledon but not the Australian Open or US Open. The confusion often arises because the media sometimes uses "Grand Slam" loosely when referring to Career Grand Slams.
Has any player won all four Grand Slams in a single year recently?
No. The last time this happened was in 1988, when Steffi Graf won all four tournaments during the 1988 calendar year. Since then, no player has managed to win all four in a single year, despite several close attempts.
How many players have achieved a Career Grand Slam?
As of 2026, 12 players have achieved a Career Grand Slam-7 men and 5 women. This includes legends like Don Budge, Rod Laver, Roger Federer, Rafael Nadal, Novak Djokovic, Serena Williams, and Steffi Graf.
What's the difference between a Grand Slam and a Career Grand Slam?
A Grand Slam specifically means winning all four major tournaments in a single calendar year. A Career Grand Slam means winning each of the four majors at least once during a player's career, but not necessarily in the same year. The terms are often confused, but they describe very different achievements.
Why hasn't Novak Djokovic won all four in one year?
Djokovic has won 24 Grand Slam titles, but he's never won all four in a single year. He came close in 2015 and 2023, winning three majors each time but missing the French Open. The French Open's clay surface is his weakest, and the physical demands of competing across all surfaces in one year make it nearly impossible for even the best players.
Who is the only woman to win all four Grand Slams in one year?
Margaret Court won all four in 1970. Steffi Graf also achieved this in 1988. Both are the only women to have completed the calendar year Grand Slam. No other female player has done it since.
