Re: oldest singles player
Youngest player just got his ranking today. I'm sure there have been younger, but he is May 1998, no one later than that has ranking. Even funnier: the kid can't hear.
Horacio Zeballos - Maximo Gonzalez - Guido Pella - Carlos Berlocq - Diego Schwartzman - Facundo Bagnis - all the other Argentinos
