Re: Sports Psychologists..
Gabriela Sabatini worked with a sports psycho, Jim Loher, before and during her US Open win, you can see him in some of her matches IIRC. It seemed to work for he re her unexpected (as she was not playing well in the previous events) win, yet they didn't end up nice as Loher wrote an article about sports psychology and included some examples of his work with Sabatini, and was it was published the Sabatinis were done with him. I'll try to get that article later.
