Overview

• On July 23, Sinner announced that Umberto Ferrara has rejoined his team after being dismissed last year following two clostebol positives.
• After a dominant 6-0, 6-2 quarterfinal win over Felix Auger-Aliassime, Sinner said he needed someone who “knows my body better.”
• Ferrara’s return coincides with Sinner’s 25-match hard-court winning streak and an 11-match overall run at the Cincinnati Open.
• Despite his reported role in providing the Trofodermin spray tied to the 2024 contamination, Ferrara faced no penalties from the ITIA or Italy’s anti-doping authority.
• The decision has reignited debate over the balance between athlete responsibility and entourage accountability in anti-doping governance.
