Nick Kyrgios has developed quite the reputation for being the bad boy of tennis over the years.The 23-year-old has made headline after headline throughout his career and seemingly always for the wrong reasons.His fiery temper all too often gets the better of him, and as a result, his image has been tarnished.There is no doubting the talent the Australian possesses, and he has the potential to become an absolute world beater if he can get his emotions in check.Despite all that, Kyrgios entered the ongoing Wimbledon in some of the best form of his career and will be confident of causing one or two upsets.And he finally found himself in the limelight for the right reasons the other day after one of his blistering serves struck a ball girl standing at the other end of the court.Kyrgios was extremely sympathetic with the young lady and made sure that she was ok before continuing with his match.The Australian was back in the news today however, after the chair umpire was forced to come down onto the court to explain the apparently tricky foot-fault rule.

However, even with that explanation, it seems Kyrgios struggled to grasp the whole concept, and was left baffled when the baseline judge called a foot fault on him.

Brilliant stuff.

Big up to the chair umpire for putting Kyrgios in his place so eloquently and again to both men for seeing the funny side of the affair.

Kyrgios went on to win the match in straight sets and secure his place in the third round of the championships.

With number three seed Marin Cilic falling by the wayside in the biggest shock of the championships so far, the talented Kyrgios will be hoping to cause a few upsets of his own in London.
