Jannik Sinner is still regaining his focus on the tennis court after his three-month doping ban. The top-ranked player overcame a brief lapse during the first set of a 6-4, 6-2 victory over Dutch qualifier Jesper De Jong in his second match back on tour at the Italian Open on Monday.

Jannik Sinner backed up his straight sets win over Mariano Navone, in his first match in three months, with another solid display against Dutch lucky loser Jesper de Jong, advancing 6-4, 6-2.

Tim Elko drilled a go-ahead, three-run home run in the sixth inning for his first career hit and Mike Vasil pitched effectively in relief to boost the Chicago White Sox to a 4-2 win against the visiting Miami Marlins on Sunday.
