The fact is and I agree with some of you that if Roddick is healthy then I would not bet against him on hard courts except when he plays Fed, Hewitt, Agassi, Safin, and maybe Johannson. The rest of the field either does not posses the serve to match Roddick or return of serve to get his his balls in play on a consistent basis. There are few others who are capable of beating Roddick on hard only if they play very very decent match : Moya, Nalbandian, Haas, Canas.
On clay it is totally different scenario. I can think of maybe 20-25 players who are easily better than Roddick. Once his serve is in play on a consistent basis, then a lot of guys out there who can compete with him from the baseline.
His top 10 results are skewed somewhat becuase most of the wins he had against likes of Coria, Moya, Nalbandian, are on hard courts and if he could make later rounds in clay events and face those guys, his results would be somewhat different.
BTW, I just checked Safin - Gaudio head to head and all of their meeting were on clay (5 meetings, Safin leads 3-2) once again because Gaudio is a clay courter and he does not reach later rounds of hard court events often.
