I have had to great opportunity to coach a girl who has reached 48 in the world on the WTA.
Her name is Vasilisa Bardina. She played Kim Clijsters in 2007 at the Australian Open. Here is the link to check out the match http://www.youtube.com/watch?v=ZNzvoMA2FsA

When Vasilisa first came to me, I told her the biggest thing to change was her tennis serve.
To be very blunt, she got to #48 in the world with a deficient tennis serve. She agreed to work with me on trying to change her tennis serve.
