Fourth-seeded Bernard Tomic has been beaten in straight sets by Thomaz Bellucci in the quarterfinals of the Shenzhen tennis tournament in China.

Tomic lost 6-2 6-2 on Friday to the Brazilian left-hander.

It was a disappointing outcome for the Australian after he had produced a composed performance on Thursday to edge out America’s Ryan Harrison 6-4 4-6 7-5 in just over two hours in the second round.

In other last-eight results, Janko Tipsarevic of Serbia beat Tunisian Malek Jaziri 7-6(6) 6-2 and No.3 seed Richard Gasquet of France downed German Mischa Zverev 7-6(4) 7-6(2).
