De Jong fell to the clay when he lost his footing trying to reach a passing shot from Sinner in the second set and the Italian came across the net to check on him. Sinner fetched a towel for De Jong and wiped off the Dutchman’s racket handle.

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.
