Jannik Sinner confirmed that he recently fired two members of his team — fitness coach Marco Panichi and physiotherapist Ulises Badio, who themselves were replacements for people involved in the player's doping case — but declined Saturday to explain the reason for the change ahead of Wimbledon.
Sinner, who has been ranked No. 1 for more than a year, said that he decided shortly after losing in the second round of the grass-court tournament in Halle, Germany, this month to make the change. Sinner has not yet found substitutes for Panichi and Badio, who both used to work with Novak Djokovic.
