Sinner not confident to continue with trainer and physio

The Straits Times

August 25, 2024

World No. 1 Jannik Sinner has announced that 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 treatment on Sinner.

The spray was given to Naldi by trainer Umberto Ferrara.

Sinner, 23, was cleared of fault or negligence by a tribunal last week, accepting his explanation that he had inadvertently been contaminated with the substance by Naldi, the International Tennis Integrity Agency (ITIA) said.

The positive doping tests came to light only on Aug 20, a day after the Australian Open champion won his fifth title of the year at the Cincinnati Open.

"They (Naldi and Ferrara) have been a huge part for my career," Sinner said on Aug 23, ahead of the start of the US Open on Aug 26.
