Nick Kyrgios fined, loses prize money for storming out of Shanghai opener

Nick Kyrgios has been fined by the Association of Tennis Professionals for unsportsmanlike conduct after walking out of his first-round match at the Shanghai Masters.

The controversial Australian stormed off the court to boos from the crowd after losing the first-set tie-break 7-5 to American opponent Steve Johnson.

Shortly after receiving a warning for whacking two balls out of the court in frustration, the 22-year-old threatened to walk away midway through the match if he lost the breaker.

Kyrgios later took to Twitter to apologise to the fans, blaming his walkout on a stomach bug.

As a result of his actions, the tennis star has been fined £7,500 and also lost £16,000 in prize money due to his failure to get signed off for a medical despite complaining of feeling poorly.

Last season at the tournament, the Australian served an ATP Tour ban for a lack of effort in a second-round match against Mischa Zverev.
