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.

World No 1 Jannik Sinner returned to the match court on Saturday, after one of the most controversial doping bans of recent memory, and immediately reverted to winning ways.

Jannik Sinner was just as surprised by which fellow players sent him messages of support at the start of his three-month doping ban as those who sent nothing.
