Nick Kyrgios storms off court in Shanghai, days after Beijing meltdown

Nick Kyrgios courted controversy once again at the Shanghai Masters on Tuesday, retiring midway through his match with Steve Johnson for seemingly no reason. The Australian enjoyed a run to the China Open final last week, only to be outclassed by Rafael Nadal after appearing to be negatively affected by a line call going against him in the opening game. In the wake of that defeat, Kyrgios revealed that his charitable foundation to help disadvantaged and underprivileged children has given him a fresh focus to motivate himself. But there was little sign of the 22-year-old turning over a new leaf as he shook hands with Johnson and promptly walked off court after losing the first set on a tie-break. (Video Credit: SNTV)
