Semi-Pro
They go by the name.
Like beating a fed is 20 times better than beating a medvedev. Upsets happen. But once matured, Fed never got challenged by this guy in slams. At all.
Nole, Rafa, Andy have positive h2h despite being youngsters. But this 1 event is all that is enough for few.
Uh, Nalbandian was on his way to beating Federer at FO 2006 then got injured.
