I would take Mendez for sure. A low top 100 isn't going to cut it unless it's supported by some strong secondary pieces. There's no reason for us to expect less than a similar value to what we got for Will Smith. Stearns has most of the leverage here. He doesn't need to aggressively shop Guerra, if the return is underwhelming he should be perfect comfortable risking the chance that Guerra will regress. The upside is that if he doesn't, he'll cost even more to interested teams at this time next season. Teams can be as skeptical of Guerra as they want, and I'm sure they will be, but the fact of the matter is that starting pitching is a huge need for many contending teams, it's a very weak FA class, and it's rare that a sub 3.00 ERA starter with basically a whole career left of cheap control becomes available in trade for less than a top 25 prospect. If teams aren't willing to value Guerra in that way despite their concerns, there's no reason for Stearns to pull the trigger now.
