NEW YORK (Reuters) - World number one Jannik Sinner announced he had fired his trainer and physiotherapist after he escaped a doping ban despite failing two drug tests in March.
The Italian tested positive for the steroid clostebol, which can be used to build muscle mass, after his physio Giacomo Naldi applied an over-the-counter spray to a cut on his own hand before carrying out treatments on Sinner. The spray was given to Naldi by trainer Umberto Ferrara.
