Sinner Rehires Ferrara After Doping Ban Shakeup

Wimbledon champion and world No. 1 Jannik Sinner has rehired his former fitness coach Umberto Ferrara, almost a year after both Ferrara and physiotherapist Giacomo Naldi were removed from his team due to a doping case. Sinner served a three-month ban after testing positive for the anabolic steroid clostebol, which authorities determined entered his system inadvertently through an over-the-counter spray used by Naldi and supplied by Ferrara. Though an independent tribunal initially cleared Sinner, he accepted the ban after a World Anti-Doping Agency appeal. Sinner cited a need for 'clean air' when restructuring his team following the incident. Ferrara's return comes as Sinner also parts ways with his latest fitness and physiotherapy staff, aiming to restore stability ahead of the Cincinnati Open and U.S. Open. The case has highlighted ongoing concerns about anti-doping protocols in tennis.
