Andre Kirk Agassi (/ˈæɡəsi/ AG-ə-see; born April 29, 1970) is an American former professional tennis player. He was ranked as the world No. 1 in men's singles by the Association of Tennis Professionals (ATP) for 101 weeks, including as the year-end No. 1 in 1999. Agassi won 60 ATP Tour-level singles titles, including eight majors, completing the Career Grand Slam. He also won an Olympic gold medal, the 1990 ATP Tour World Championships, 17 Masters titles and was part of the winning United States Davis Cup teams in 1990, 1992 and 1995. Agassi is one of eight men in history to win the Career Grand Slam in singles, and one of three men to complete the career Golden Slam in singles.
A teenage phenomenon, Agassi contested multiple major finals before winning his first at the 1992 Wimbledon Championships. His ranking thereafter dropped afterward due to surgery, but he recovered and won the 1994 US Open and 1995 Australian Open to reach the world No. 1 ranking for the first time. He was then troubled by personal issues during the mid-to-late 1990s, and despite an Olympic gold medal at the 1996 Atlanta Olympics, Agassi's ranking declined to as low as No. 141 in 1997, prompting many to believe that his career among the elite was over. Following a rigorous training regimen, Agassi then enjoyed the most successful run of his career over the next several years. He returned to the world No. 1 position in 1999 after completing the Career Golden Slam at the French Open, and during this latter half of his career also claimed a US Open title and three Australian Open titles. Competing well into the 2000s, Agassi retired from the sport following the 2006 US Open.
The Davis Cup is the premier international team event in men's tennis. It is organised by the International Tennis Federation (ITF) and contested annually between teams from over 150 competing countries, making it the world's largest annual team sporting competition. It is described by the organisers as the "World Cup of Tennis" and the winners are referred to as the world champions. The competition began in 1900 as a challenge between Great Britain and the United States. Initially titled the International Lawn Tennis Challenge, it soon became known metonymically after the trophy donated by Dwight F. Davis; the name was officially changed after Davis' death in 1945. By 2023 155 nations entered teams into the competition.
The most successful country over the history of the competition is the United States (winning 32 titles and finishing as runners-up 29 times). The most recent champions are Italy, who beat Spain to win their fourth title (and third consecutive one) in 2025.
