Nick Kyrgios: Is Australian world number 14 wasting his talent?

At the Shanghai Masters on Wednesday he did not just lose to a man ranked almost 100 places below him, having won his preceding tournament in magnificent style, but seemed to scuttle himself mid-battle: patting the ball over the net rather than serving, walking back to his chair before a serve from his opponent had landed, arguing with the umpire, arguing with spectators, swearing to all quarters.

A very Kyrgios thing, followed by a very Kyrgios reaction: internet outrage, opprobrium from former players, condemnation from those in Australia convinced he is both betraying his own talent and the accepted sporting ethos of their nation.(BBC,2016)
