Jannik Sinner is still regaining his focus on the tennis court after his three-month doping ban. The world No. 1 overcame a brief lapse during the first set of a 6-4, 6-2 victory over No. 93 Dutch qualifier Jesper De Jong in his second match back on tour in front of his home crowd at the Italian Open on Monday.

Jannik Sinner returned from his three-month doping ban on Saturday, beating Mariano Navone in straight sets before a supportive home crowd at the Italian Open.

World number one Jannik Sinner was ecstatic after a victorious return following a three-month doping ban, with a 6–3 6–4 win over Argentina's Mariano Navone in the second round of the Italian Open. Sinner agreed a settlement with the World Anti-Doping Agency in February and began an immediate three-month suspension after authorities accepted that the anabolic agent clostebol had entered his system via massages from his physiotherapist.
