Wimbledon 2012: Katy Dunne fired up by umpire decision

Katy Dunne tells BBC Sport an umpire call she did not agree with only made her more determined to reach the girls' second round.

Dunne believed she had at least a point to play in the third game when it was awarded to her opponent Chalena Scholl.

The Hertfordshire teenager beat her American opponent in straight sets to set up a tie with Petra Uberalova of Slovakia.
