Happy birthday to Monica Seles, the youngest player ever, at age 16, to win the French Open. She followed up that 1990 victory with French Open and U.S. Open wins in 1991 and 1992, in addition to 1991, 1992, 1993, and 1996 Australian Open wins. Besides those nine Grand Slam singles titles, she also won a bronze medal at the 2000 Olympics. Seles career was halted when she was stabbed during an on-court attack, and though she returned to the game some years later, she was never able to fully regain her status. The stories of her successes and No. 1 ranking, however, live on.
