3rd is 100 % more difficult to field then 2nd
Ummmm....not really. I play both fairly regularly and 2nd base has far more responsibility than does 3rd.
But I do agree that Zimm is a better defensive player than Uggla....
Anybody who knows anything about Baseball knows that 3B is the hardest position to field. Ball comes at you quicker than any other spot on the field, which means less time to react.
And I'm telling you as a person who has played both positions already this year (IN BASEBALL - NOT SOFTBALL) that 2nd is the much more difficult position. I was hit in the face with one-hopper off the dirt at 3B last year and I finished the game.
Yes, the ball comes at you faster and you need to have quick reactions and a strong arm. But second is a far more difficult position to play with all of the cutoff, coverage and double-play responsibilities.
Do you even play? If you do, have you played 2nd or SS?
EDIT:
And further "the hardest position on field" is CATCHER. Anyone who actually plays KNOWS that.
