Yea four. Before his coach died. It was when Annacone took over he quit giving two craps about clay. Anyways.. Im not denying Fed is a better dirt baller than Sampras. I just hate when people make stupid comments like, "Sampras sucked on clay, he never accomplished" anything.. yada yada without looking at some of the facts, the era, his draws etc. And besides, Its not like Fed is a god on clay either.
