The Italian Jannik Sinner, sixth player in the world, qualified for the third round of the US Open tennis on Thursday after beating his compatriot Lorenzo Sonego (N.39), 6-4, 6-2, 6- 4. After a sluggish start to the match, Sinner set up his game, with power contrasting with his frail physique.

Sonego tried to wrap the trade, run Sinner, but the recent Toronto tournament winner pitted him against his positional sense, serve and ability to take the ball early. Rather known for his baseline game, the recent Wimbledon semi-finalist also took the initiative at the net, successfully (22 points out of 25 mounted). “My game has improved,” said the Italian after his victory. “I feel more comfortable at the net.”

In the third round, Sinner will be opposed to the winner of the meeting between the Argentinian Thomas Etcheverry (N.34) and the Swiss Stan Wawrinka (N.49).
