Grand Slam (tennis) champions in men's singles

Michael Te-pei Chang (born February 22, 1972) is an American former professional tennis player and coach. He is the youngest man in history to win a singles major, winning the 1989 French Open at 17 years and 109 days old. Chang won a total of 34 top-level professional singles titles, (including seven Masters titles) was a three-time major runner-up, and reached a career-best ranking of world No. 2 in 1996. Since he was shorter than virtually all of his opponents, he played a dogged defensive style utilizing his quickness and speed.
In 2008, Chang was inducted into the International Tennis Hall of Fame. He began coaching Kei Nishikori in 2014.

Gustavo "Guga" Kuerten (Portuguese pronunciation: [ɡusˈtavu ˈkiʁtẽ]; born 10 September 1976) is a Brazilian former world No. 1 tennis player.

Kuerten suffered from injuries that limited his attendances at tournaments in 2002 and from 2004 and 2008. After two hip surgeries and a few attempted comebacks, he retired from top-level tennis in May 2008. He was inducted into the International Tennis Hall of Fame in 2012. In 2016, Kuerten was asked to be a torch bearer for the Rio Olympics.

John Donald Budge (June 13, 1915 – January 26, 2000) was an American tennis player. He is most famous as the first tennis player — male or female, and still the only American male — to win the Grand Slam, and to win all four Grand Slam events consecutively overall. Budge was the second man to complete the career Grand Slam after Fred Perry, and remains the youngest to achieve the feat. He won ten majors, of which six were Grand Slam events (consecutively, a men's record) and four Pro Slams, the latter achieved on three different surfaces. Budge is considered to have one of the best backhands in the history of tennis, with most observers rating it better than that of later player Ken Rosewall.Budge is also the only man to have achieved the Triple Crown (winning singles, men's doubles and mixed doubles at the same tournament) on three separate occasions (Wimbledon in 1937 and 1938, and the US Championships in 1938), and the only man to have achieved it twice in one year. Budge was the world Number 1 amateur in 1937 and 1938 and world Number 1 professional in 1939, 1940 and 1942.

As a member of the French team, Lacoste won the Davis Cup in 1927 and 1928. Lacoste was the World No. 1 player for both 1926 and 1927. He also won a bronze medal at the 1924 Summer Olympics.
