I was pondering this idea for next season, if we don't pick anyone up in the infield and the INF roster stays the same. Why not try Edwin out at first base a little bit. It's obvious that he has great range, but I've seen him bounce a lot of long throws to first or make throws that pull the first baseman off the bag. Being at first he would still be able to show off his range and you'd eliminate a lot of throwing for him.
If our roster looks the same next year, I wouldn't mind trying something like Hatte at 3rd, BP at SS, Aurilia at 2nd and Edwin at 1st. Just a thought, because I'd like to see how it would work out, I don't know about moving someone like Hatteberg though and I know we have him signed through next year.
