Nick Kyrgios ended his Shanghai Masters campaign in lacklustre fashion as he appeared to give up during his second-round match against Mischa Zverev.

At one point, the 21-year-old, who has previously reached the quarter-finals of the Australian Open and Wimbledon, walked off the court before a return was hit.

During a changeover, the Australian was also heard asking the umpire, "Can you call time so I can finish this match and go home?"

In the end, Kyrgios, who won the Japan Open in Tokyo last weekend, recorded a 6-3 6-1 defeat to Zverev - ranked 110th in the world.

Kyrgios lost serve five times throughout the match and could only convert one break point.
