I said send to St. Paul. Then I gave it more thought.....
Send Miranda down. Move Gio to first, and put Lewis at 3B most days. Give CC a day a week at DH and put Lewis at SS that day.
Also, AK needs to be in ST Paul to get his groove back (or not).
I'd also consider Larnach for DH/1B once a week with Lewis in LF.
I guess I'm saying, keep Lewis up and see what he's got. Mostly at 3B and subbing in at SS. If I had any idea if playing LF or 3B would help Lewis play SS better next year (just in case....), I'd put him at that spot this year.
