Player served three-month suspension over positive test
Umberto Ferrara blamed incident on physiotherapist
The Wimbledon men’s singles champion, Jannik Sinner, has reappointed his former fitness coach Umberto Ferrara with immediate effect, the Italian world No 1 confirmed on Wednesday.
Sinner parted ways with Ferrara and physiotherapist Giacomo Naldi last year following the investigation into his positive tests for the banned substance clostebol. “The decision has been made in alignment with Jannik’s management team as part of ongoing preparations for upcoming tournaments, including the Cincinnati Open and US Open,” a statement from Sinner’s team said. “Umberto has played an important role in Jannik’s development to date, and his return reflects a renewed focus on continuity and performance at the highest level.”
Sinner served a three-month suspension earlier this year after agreeing a settlement with the World Anti-Doping Agency (Wada) in February after authorities accepted that the anabolic agent clostebol had entered his system inadvertently via massages from Naldi at Indian Wells in March 2024.
