Re: David limping through Cincy.
I agree. I have never heard Rafa curse. He sometimes gets a little angry with himself, and makes an "oh, oh" face, but that's it. I think Roger got mad enough to curse once, during the U.S. Open final with Del Potro.
Fernando Verdasco spit on court after losing to Rafa, very unsportsmanlike behavior. Feli dropped the "J-bomb" on one occasion, too.
I wonder if Juan Carlos has ever talked to Ferru about his cursing on court? Juanqui seems like a quiet sort and I have never heard him curse, at least not during a match in a major tournament.
