Answer: Anna Kournikova
The blonde bombshell would never win a singles title in her professional career, but she did reach No. 8 in the world at one point in her short career. Her greatest on-court achievements came during doubles play, where she was ranked #1 worldwide with superstar partner Martina Hingis. They won multiple Grand Slam titles and WTA championships as a team that many people referred to as the “Spice Girls of Tennis”. Her pro career was unfortunately cut short at the young age of 21 because of back and spinal problems, which included a herniated disk.
