I thought of this topic a while ago, but I was going to let StickRat finish all the positions.  I think he just didn't bother with the outfield. 

Basically, I couldn't help but notice that under the definition "You don't have to have a reason, just pick your favorite" criteria, most of us went with the player who held the position when we were growing up and falling in love with baseball. 

I'm curious who we chose (or would have chosen in the OF) that came later in our respective fan careers. (Or before your time, if you roll that way.)

(Note:  This isn't a request to list 11 positions with players that meet that criteria.  It's a request to see how many of your 11 just happen to.)

OK, I'll go first.

2B:  Robby Thompson
SS:  Omar Vizquel
3B: Matt Williams
LF:  Barry Bonds
RHSP:  Tim Lincecum
LHSP: Atlee Hammaker, before he fell apart.

Everyone else was playing before I was 16.
