Nick Kyrgios said he wanted to make up for his notorious meltdown last year in Shanghai as he beat Mischa Zverev in the second round of the China Open on Wednesday.

A year ago the supremely talented but combustible Kyrgios was suspended for his petulant behaviour at the Shanghai Masters, where he swore and argued with the crowd and appeared to give away points in caving in to the German. The enigmatic Australian, seeded eighth on Beijing's outdoor hard courts this year, smashed his racquet on the floor in anger, bending the head in half, when he conceded the opening set on Wednesday.
