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.

This was Jannik Sinner's 50th victory as the ATP's top-ranked player, in just his 53rd outing as the world number one. Since the ATP rankings were first published in 1973, that is the joint-fewest matches required to reach 50 wins as the world number one,

Carlos Alcaraz saved two break points early in the third set then dropped his serve later on to waste an early break before improving to 5-0 in his career against the 24th-ranked Karen Khachanov.
