Monica Seles (born December 2, 1973) is a retired professional tennis player, who represented Yugoslavia and the United States. An ethnic Hungarian, she was born and raised in Novi Sad, Yugoslavia (now Serbia). She became a naturalized American citizen in 1994 and also received Hungarian citizenship in June 2007. A former world no. 1, she won nine Grand Slam singles titles, eight of them as a teenager while representing Yugoslavia, and the final one while representing the United States.
In 1990, Seles became the youngest-ever French Open champion at the age of 16. She went on to win eight Grand Slam singles titles before her 20th birthday and was the year-end world no. 1 in 1991 and 1992. However, on April 30, 1993, she was the victim of an on-court attack, when a man stabbed her in the back with a 9-inch (23 cm) long knife. Seles did not return to tennis for over two years. Though she enjoyed some success after rejoining the tour in 1995, including a fourth Australian Open title in 1996, she was unable to consistently reproduce her best form. She played her last professional match at the 2003 French Open but did not officially retire until February 2008.
Seles played her first professional tournament as an amateur in 1988 at age 14. The following year she turned professional on February 13, 1989, and joined the professional tour full-time, winning her first career title at Houston in May 1989, where she beat the soon-to-retire Chris Evert in the final. A month later, Seles reached the semifinals of her first Grand Slam singles tournament at the French Open, losing to then-world no. 1 Steffi Graf. Seles finished her first year on the tour ranked world no. 6.
From January 1991 through February 1993, Seles won 22 titles and reached 33 finals out of the 34 tournaments she played. She compiled a 159–12 win-loss record (92.9% winning percentage), including a 55–1 win-loss record (98%) in Grand Slam tournaments. In the broader context of her first four years on the circuit (1989–1992), Seles had a win-loss record of 231–25 (90.2%) and collected 30 titles. She once again ended the year as the #1 ranked player in the world.
Regarded by many in the sport as one of the greatest tennis players of all time, Seles was named one of the "30 Legends of Women's Tennis: Past, Present, and Future" by Time. Several players and historians have stated that Seles had the potential to become the most accomplished female player of all time had she not been stabbed. She was inducted into the International Tennis Hall of Fame in 2009.
