Following the widespread flooding in Queensland several players decided to raise money for the cause . The Association of Tennis Professionals and the Women 's Tennis Association donated ten dollars for every ace served during the Australian Open and as well as during the two pre tournament joint events in Brisbane , before the Pat Rafter Arena was flooded four days after the conclusion of the 2011 Brisbane International , and Sydney . In Brisbane , Andy Roddick and Sam Stosur pledged a hundred dollars for every ace they hit , which was also matched by Australian player Matthew Ebden when he played in Sydney the following week . Roddick later doubled his pledge to two hundred dollars . In total Roddick hit fifty four aces , raising just under eleven thousand dollars for his efforts during the Brisbane tournament . In addition to this the Brisbane International donated another five thousand dollars . While American Bethanie Mattek-Sands pledged to donate five percent of her prize money from the Hobart International and Australian Open to the cause . Mattek – Sands move was similar to a gesture that she conducted to help the victims of the Nashville floods in 2010 . As well the ITF donated $ 25,000 towards the rebuilding of tennis facilities . In total from the ATP and WTA 's $ 10 per an ace drive they managed to raise $ 51,070 while Roddick donated over $ 10,000 from his personal pledge
