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.

She won the Junior Orange Bowl in both the 12- and the 14-year categories, and is one of only nine tennis players to win the Junior Orange Bowl championship twice in its 70-year history, which list includes Andy Murray, Jimmy Connors, Monica Seles, and Yishai Oliel.  Capriati made her professional debut as a 13-year-old, reaching the finals of two of her first three pro events, losing to Gabriela Sabatini and Martina Navratilova in the Boca Raton and Hilton Head tournaments respectively, earning her first two wins over top-10 players (No. 10 Helena Sukova and number-five Arantxa Sanchez Vicario). She entered the rankings in April, at No. 23. Capriati made her Grand Slam debut at the French Open. She went all the way to the semifinals, losing to eventual champion Monica Seles. She then reached the fourth round at Wimbledon, losing to Steffi Graf. Later in the year Capriati won her first career title in Puerto Rico, defeating Zina Garrison. After this victory Capriati entered the world's top 10. She qualified for the WTA Championships, narrowly losing to Graf in the first round in three sets. She finished her first season as a professional at World Number Eight.  Throughout the season Capriati set multiple "youngest ever" records. She was the youngest player to reach a tour final, the youngest player to reach the semifinals at the French Open, the youngest seed ever at Wimbledon, and the youngest player to qualify for the season-ending championships. She was also the fourth-youngest player to win a WTA title.  In her second season as a touring pro, Capriati established herself as a consistent top-10 player. She won two singles titles during the summer hard court circuit, defeating World No. 1 Monica Seles in a third set tie-breaker in finals of San Diego, and Katerina Maleeva in straight sets in the final of Toronto. She also reached two Grand Slam semifinals, at Wimbledon and the US Open. At Wimbledon, the 15-year-old Capriati stunned nine-time champion Martina Navratilova, defeating her in the quarterfinals in straight sets. Capriati became the youngest person to ever reach the semifinal round of the tournament, losing to Sabatini. At the US Open, Capriati defeated Sabatini in the quarters but lost in the semis to eventual champion Seles after serving for the match twice. Capriati qualified for the year-end championships for the second time, reaching the quarterfinals. She ended the year at No. 6, which would be a career high until 2001.  Capriati also won the only doubles title of her career at the Italian Open, partnering with Seles.Answer this question using a quote from the following article:
