During the Serena vs. Venus match at the BNP Paribas Showdown for the Billie Jean King cup, Serena's conditioning coach, Mackie Shilstone, said the following:
"I joined Serena's team a year ago after the '08 Australian Open. She's an extremely talented athlete, one of the best I've ever seen."
On what he plans to add to her game:
"I think the thing I may do is giver her a little more consistency. She already has all the talent in the world. If I can allow her talent to be magnified to let Serena Williams be Serena Williams I think I've done my job."
