Overview

• Umberto Ferrara has rejoined Jannik Sinner’s staff after being dismissed in August 2024 over his role in supplying a Clostebol-containing spray.
• Ferrara’s spray was cited in Sinner’s positive March 2024 Clostebol test that triggered a three-month ban earlier this year.
• The management statement praises Ferrara’s contribution to Sinner’s development and consistency but omits any reference to the doping case.
• Sinner resumed competition post-suspension with notable showings at the Rome Masters and a Wimbledon title that secured his world No. 1 ranking.
• The decision comes as Sinner’s camp gears up for the North American hard-court swing, including the Cincinnati Open and US Open.
