Italian junior kicked out of Australian Open after hitting ball kid

Teenage Italian tennis player, Maria Vittoria Viviani, has been sensationally kicked out of the Junior Australian Open after hitting a ball kid with a ball.

Viviani, 17, hit a ball away in disgust after losing the first set of her round one tie with China's Xin Yu Wang.

The ball apparently hit the ball kid softly in the chest and Viviani immediately apologised for her actions. 

The chair umpire didn't show any leniency though, disqualifying the Italian on the spot.
