Jannik Sinner passed a big test in his return from a three-month doping ban, beating accomplished clay-court player Francisco Cerundolo on Tuesday to reach the Italian Open quarterfinals.

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 appears to have overcome his latest 'ban' after he was spotted meeting the new Pope at the Vatican. The three-time Grand Slam winner is currently playing at the Italian Open, his first tournament since returning from a doping suspension. He is through to the quarter-finals in Rome and will face Casper Ruud in the last eight.
