WADA wants lengthy ban if swim star Sun loses doping hearing

LAUSANNE, Switzerland (AP) — The World Anti-Doping Agency wants China’s star swimmer Sun Yang banned for up to eight years for alleged doping rules violations.
The Court of Arbitration for Sport said Tuesday ahead of a rare appeal hearing in open court on Friday that WADA requests a ban of two to eight years. Sun served a three-month ban in 2014 for a positive test.
If WADA wins, the three-time Olympic freestyle champion will miss the 2020 Tokyo Games.
