Monica Seles is a retired professional tennis player who represented Yugoslavia and the United States. She was ranked as the world No. 1 in women's singles by the Women's Tennis Association (WTA) for 178 weeks (sixth-most of all time), and finished as the year-end No. 1 three times. Seles won 53 WTA Tour-level singles titles, including nine majors: eight as a teenager while representing Yugoslavia and the final one while representing the United States.
A teen phenomenon, Seles became the youngest-ever French Open champion in 1990 at 16. She went on to dominate the women's circuit in 1991 and 1992, compiling a total of eight major championships while still a teenager. However, on April 30, 1993, Seles was the victim of an on-court attack when an obsessed fan of Seles' rival Steffi Graf stabbed Seles in the back with a knife as she was sitting down between games. Seles did not play professional tennis for over two years following the stabbing, struggling with depression and an eating disorder. After returning in 1995, Seles claimed a ninth major championship at the 1996 Australian Open, but was unable to consistently produce her best tennis.
