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.

Alcaraz, who won the Monte Carlo Masters in April, improved to 12-1 on clay this season. The four-time Grand Slam champion will next face No. 5 Draper, who rallied past Corentin Moutet 1-6, 6-4, 6-3 on the red clay courts of the Foro Italico.
