There's a guy in Ripken Jr who has done it. He had to slide his 3b over to SS this season and had a real crappy guy playing 3b for much of the year, but once he corrected it, he almost made up enough ground to grab the wild card. Last season w/ a better SS/3b options defensively he ran to the 2nd best record in the league. He plays in KC (pitchers park) and his offense scored a bunch of runs. However my fear that proved to be correc last year (granted small sample size) was that w/o more power (he had 2 big boppers but everyone else was speed/speed/speed) he would struggle vs better pitchers/catchers in the playoffs. He got bounced in year 1. Still, though he has a pretty good handle on it, just needs a little more OBP I think to make things work (and better defense at SS/3rd than he had this season) Its irock's KC team in Ripken, JR if you want to have a look, though we're about to end the WS soon (I'm up 3-1 w/ game 5 tonight) in a private world, so you may not be able to access them for too long once the world flips.
