# Tennis: Jannik Sinner of Italy will be certain of retaining the number one world ranking when he returns from his three-month doping suspension early next month. Alexander Zverev of Germany’s loss to Sinner’s compatriot, Matteo Berrettini, in the round of 32 in the Monte-Carlo Masters means he won’t be able to overtake Sinner. Zverev failed to advance beyond the quarterfinals of his last six tournaments. Twenty-three-year-old Sinner plans to return to the circuit in the Italian Open, starting in Rome on the fifth of May.
