Lewis, Lewis, Lewis.
After that? Celestino will hopefully play well this year in St. Paul. I'd also promote kiersey to AAA to see what he's got, but until they finally move on from Kepler and Gallo, there is no room for him.
My next choice is Martin, who should have been an outfielder the last two years, but for some weird reason wasn't.
No way I trade for one or sign one. Give the youth you've acquired a chance. If the FO doesnt believe in any of them, they don't believe in themselves....
