Nick Kyrgios added another weird chapter to his tormented career. On Tuesday in Shanghai, the Australian walked out the court for apparently no reasons after he lost the first set against Steve Johnson.

Few hours after the incident, Kyrgios explained that he was struggling with a bug, but the excused wasn’t accepted by the ATP also because Nick didn’t want to see any doctor after his retirement and while on court, he seemed to be annoyed by some calls and the spectators.

The ATP fined the American $31,085 ($21,085 was his prize money + $10,000 for unsportsmanlike conduct). 

That’s pretty big stuff.
