Serena Williams calls tennis anti-doping system unprofessional ahead of Wimbledon return

Serena Williams criticized tennis' anti-doping system as unprofessional and unreasonable on Sunday ahead of her return to Wimbledon. The 44-year-old returned to the testing pool before announcing her comeback to professional tennis.

She stated that strict testing procedures were a major reason for delaying her return to the sport.

  • Wimbledon has been held annually since 1877 and remains the only major tennis tournament still played on natural grass.
  • Anti-doping testing in tennis follows the World Anti-Doping Agency's global standards for professional athletes.
  • Williams won 23 Grand Slam singles titles before retiring from professional tennis in 2017.
