DBacks Looking for SS, Veteran SP, 3B

Awhile back we were kicking around trade ideas for Justin Upton from the Diamondbacks. GM Kevin Towers' postseason press conference confirms much of our speculation:

Towers identified shortstop (no surprise), a veteran starter (mild surprise), third baseman (mild surprise) and bullpen help (no surprise) as his off-season wish list. I’m not sure if that’s in order of priority, but shortstop definitely belongs at the top of the list.

The article also confirms they are trying to make room for Adam Eaton in their starting outfield, leaving Kubel, Gerardo Parra, Chris Young, and maybe even Upton as potential trade bait. If the Cubs were willing, I think a Castro/Garza for Upton/Corbin framework would have legs.
