Simona Halep, the former Wimbledon and French Open champion tennis player, has expressed dismay at the way Iga Swiatek's doping case was handled compared to her own. Halep, a 33-year-old Romanian who initially received a four-year ban for doping, said there had been severe differences in how their cases were treated by tennis authorities. “I sit and try to understand but it is really impossible for me to understand something like this," Halep posted Friday on her Instagram account.
