Lueke was jailed for rape not long ago. It does seem an odd decision by the Rays.
He does have good strikeout and walk numbers in the minors and is a big man. Looks like an effort to find some talent for the bullpen-or perhaps for AAA to see if he can force his way into the majors. I am not surprised that Jaso was dealt; I think Maddon was disgusted by his defense last year.
