The world No. 1 was rusty on his first match back after three months away. His Italian Open draw means he cannot afford to be so for long.

Jannik Sinner made his way through to the quarters in Rome after beating Argentina’s Francisco Cerundolo 7-6 (7-2), 6-3 on Tuesday at Centre Court.

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.
