You can check out the records. Babe Ruth played in the 1910's and he's recognized as perhaps the greatest ever.
Tilden's records are easily available for example. By record for clay I do think he's top ten. He won a ton of clay events and the World Hardcourt which was the equivalent of the French Open today.
