Who was the first man to complete a career Golden Slam in singles?

Andre Agassi was the first man to complete a career Golden Slam in singles.

A career Golden Slam requires winning all four Grand Slam tournaments—the Australian Open, French Open, Wimbledon and US Open—plus an Olympic singles gold medal during a player’s career. Agassi completed the achievement at the 1999 French Open, when he defeated Andriy Medvedev in the final and added the one major title missing from his collection.

His Olympic gold had come earlier, at the 1996 Atlanta Games. Agassi had already won Wimbledon in 1992, the US Open in 1994 and the Australian Open in 1995, so his French Open victory completed both his career Grand Slam and the Olympic-inclusive Golden Slam.

The achievement is different from a calendar-year Golden Slam, which requires all four majors and Olympic gold in the same year. Steffi Graf achieved that much rarer feat in 1988. Agassi’s accomplishment was a career milestone, later matched by Rafael Nadal and Novak Djokovic among men. Agassi also became the first man to complete a career Super Slam by adding the year-end championship to the four majors and Olympic gold.
