Has anyone won all 4 Grand Slams in the same year? Here’s a look at the 5 players who have made history by winning all four Grand Slams in a single calendar year. Steffi Graf 1988 was a truly special year for Steffi when she did the unthinkable and completed the Golden Grand Slam by winning all four Grand Slams and gold at the Olympic Games. Steffi Graf is considered by many to be Germany’s greatest-ever tennis star. In 1988, she lived up to this claim by not only winning the four major Grand Slams, but also by winning gold at the summer Olympics and securing the WTA Tour Championships, aged just 19. She would continue to add Grand Slams to her resume, winning four more between 1993 and 1994. She would retire in 1999, aged 30, while ranked as No. 3 in the world. What an amazing athlete. oing back a couple of decades before Venus and Serena burst onto the scene, however, we have Margaret Court. Margaret, aged just 20, won 4 consecutive Grand Slams in 1970, in one of the most amazing years of any pro athlete in any sport. Court is one of the greatest female tennis players to ever pick up a racket. She is also the only player to have ever won the Boxed Set not once, but twice. When a player wins a Boxed Set, this means that they have won all of the events in all of the slams, including the singles, doubles, and mixed doubles. At the time, she was also one of the youngest tennis players to have ever completed a career Grand Slam.

Maureen Connolly Brinker, 1953 In all, Maureen would win 9 singles titles over the course of her career, though her best competitive year came in 1953 when she completed all four Grand Slams in a calendar year. While the tennis world loves a rivalry, rivalries such as Federer vs. Djokovic, Federer vs. Nadal, and of course, Borg vs. McEnroe have created some wonderful tennis moments; in the 1950s, it was Maureen Connolly Brinker vs. Doris Hart that was the tennis rivalry of the decade. In her Grand Slams winning year, Maureen would face Doris Hart in 3 out of the 4 finals without even losing a single set. Even before her Calendar Grand Slam, Maureen was an incredibly successful tennis star, as she had won 3 Grand Slams before. In 1953, she also made history because she was the only woman to have ever completed a Career Slam. Her on-court rival Doris Hart, however, would repeat this feat to become the second woman to achieve this the following year in 1954. The records don’t stop there, however, as Connolly Brinker became the youngest player to ever complete a Calendar Slam, aged just 18. Don Budge, 1937 American tennis player, Don Budge is one of the most respected players in the history of the sport. He picked up numerous titles and accomplishments to help back prove why that is. Don made history in 1937 when he became the first tennis player to ever achieve a Calendar Grand Slam. To this day, he is still the only male singles competitor to win 6 consecutive Grand Slam titles, beginning in Wimbledon in 1937, and ending in the US, at the US Open in 1938. Budge was just 23 years of age when he achieved his Calendar Grand Slam, and many predicted amazing things for this young athlete. Sadly, because of the Second World War, many Grand Slam Tournaments couldn’t be held for much of the 1940s, so Don missed what would surely have been the peak of his athletic career. Despite this, making history with a Calendar Grand Slam and 6 consecutive Grand Slam wins is nothing to be sniffed at, and that’s putting it incredibly mildly. Rod Laver, 1962 and 1969 While Federer, Djokovic, and Nadal are considered by many to be the best tennis players ever, Rod Laver, in the eyes of many old-school tennis fans, is the greatest singles tennis player of all time. Rod won 11 Grand Slam titles over the course of his career, including 2 Calendar Grand Slams in 1962 and 1969. To win one is incredible, but to win two, seven years apart, shows just what an amazing athlete he was and what a gifted tennis player the Australian was. This people has a record , when it comes to All 4 Gland Slams in the same year.
