Jennifer Maria Capriati (born March 29, 1976) is an American former professional tennis player. A member of the International Tennis Hall of Fame, she won three singles championships in Grand Slam tournaments, was the gold medalist at the 1992 Summer Olympics, reached the World No. 1 ranking, and is considered one of the greatest tennis players of all time. Capriati set a number of youngest-ever records at the start of her career. She made her professional debut in 1990 at the age of 13 years 11 months, reaching the final of the hard-court tournament in Boca Raton, Florida.

Injuries plagued Capriati's 2004 season. A back injury suffered during the 2003 WTA Tour Championships forced Capriati to withdraw from the 2004 Australian Open and the Toray Pan Pacific Open in Tokyo. Capriati advanced beyond the quarterfinals just once in her first four events of the year in Doha, losing to Anastasia Myskina in the semifinals. Her back continued to be an issue, forcing her out of Indian Wells and Miami. Her ranking dropped to No. 10 as a result of her injuries. Capriati produced her best results of the year during the European clay-court season. She reached the semis of Berlin, defeating world No. 5 Myskina in the quarters for her first top 5 win of the season, before losing to Mauresmo in the semifinals. At the Italian Open, Capriati defeated top seed Serena Williams in the quarterfinals, her first win over the American since Wimbledon 2001. Capriati moved on to the final, where she lost to Mauresmo in a 3-hour struggle. Seeded 7th at the French Open, Capriati went on to the semifinals, before losing to sixth seeded and eventual champion Myskina in straight sets. At Wimbledon, Capriati reached the quarters for the fourth straight year, where she lost to Serena Williams in 45 minutes, the most lopsided result of their 17-match rivalry. A hamstring injury forced her to withdraw from Los Angeles and San Diego, but she reached the quarterfinals of both Montreal and New Haven. Seeded 8th at the US Open, Capriati defeated Williams in a controversial line call quarterfinal match to reach her fourth US Open semifinal. Capriati then lost to fifth seed Elena Dementieva in the last four in yet another, her third, tight US Open semifinal tiebreak, replicating the result in the tournament from the year before. Capriati had reached the semifinals of the US Open four times in her career (1991, 2001, 2003 and 2004), losing to a different opponent each time. Three of those times (1991, 2003 and 2004), she had lost in tough third-set tiebreaks, and two of those three opponents (Monica Seles in 1991, and Justine Henin in 2003) had then gone on to win the final and US Open championships easily in straight sets thereafter. Following the US Open, Capriati lost in the quarterfinals of Philadelphia to World No. 11 Vera Zvonareva, her worst loss since 1999 (where she won only one game against Graf in Miami). Capriati failed to qualify for the season-ending championships for the first time since 1999 and finished the year World No. 10. CANNOTANSWER
