Career Stats: 10 Grand Slams
Injury: Stabbed in the back
In 1993, Monica Seles was nineteen and the top women's tennis player. She was fresh off of winning the French Open three years in a row and was looking to continue her dominance. That was until April 30, 1993 in Hamburg, Germany. During a quarter-final match vs. Magdalena Maleeva a crazed fan stormed the court and stabbed Seles between the shoulder blades. The man was said to be a Steffi Graf fan, her rival at the time, and never served jail time for the incident due to mental instability. Her injury wasn't life-threatening, but she never recovered psychologically. Seles made a comeback two years later and even won the 1996 Australian Open. She is still widely considered to be one of the greatest tennis players of all time solely based on her first five years.
