Commentators were in hysterics as Nick Kyrgios left the court at the Cincinnati Masters and destroyed two of his rackets, before returning with what was left of them.Kyrgios' anger spilled over as he lost his second round tie in three sets to Russia's Karen Khachanov.After losing the second set, the Australian defied the wishes of Irish umpire Fergus Murphy and left the court to relieve his anger in the corridor, a change of scenery from the court, where he usually breaks his rackets.Kyrgios' antics continued into the third set, after which he branded umpire Murphy a "tool".Twenty three-year-old Khachanov dominated the final set to win 6-7, 7-6, 6-2 and advance through to the competition's third round.

After the contest, Khachanov said Kyrgios has "great talent" but "sometimes the head is not in the right place".

Kyrgios' actions are the most recent of what is a string of incidents in recent months, having clashed with Murphy at the Washington Open two weeks ago and swearing at an official at Queen's in June.

The 24-year-old began to have issues this time during the second set, claiming the shot clock, which counts down the seconds allowed between points, was being started too early.

This quickly led to a court violation for his broken rackets and a rant at umpire Murphy, whose umpiring was labelled as "the worst, hands down" by the world No.27.

Kygrios' latest court violation goes onto an increasingly large list of disciplinary action taken against him in his career.

In 2016, he was slapped with an eight-week ban for his conduct at the Shanghai Masters, where the effort he put in during his defeat to Mischa Zverev was questioned.

At Queen's in June, Kyrgios was fined over £13,000 for unsportsmanlike behaviour.

At the Italian Open in May, he was fined after kicking a bottle, throwing his racket and hurling a chair before defaulting in the final set.

Having won his sixth ATP singles crown in Washington two weeks ago, it's clear Kyrgios has the talent to become more successful in singles competition, but the question remains, when will he tone down his court antics and reach his potential.
