you found the MD
ATP doesn't show it in their fact shit
Harel Srugo is ISR and you mistyped
as for Olivo, i saw him live last year i think (or 2 yrs ago?) he looked raw to me, futures level. then again, he looked like he needed small weak challengers like air to slowly estabilish and gain experience... otherwise he'd get killed by the big guys.
i mean, a guy like Prodon can play ATP level of tennis (rarely does these days, but it's insignificant)... then there's Kavcic often paying visit to south america, or Bolelli... all of them are just different league... (doesn't matter what shape they are in)
