Sincerely, do correct me if I'm wrong on any of the below points:
1. One area in which the Twins' minor leagues is stocked is middle infielders.
2. It is easier to move a SS to 3B than vice-versa.
3. As many posters have suggested, selling EE now would be selling high.
Just my two cents, but if the Twins could get someone (anyone) who would rank around 20-25 on an updated prospect rating, I'd sell.
