Walker vs. Palka is interesting as both have undeniable power (with Walker being a bit better there) but some plate coverage/discipline issues (with Palka being better there). Not quite certain there is room on the roster for both, and both will struggle for playing time as long as Kepler and Rosario are healthy and continue to produce. One of those two could supplant Grossman at some point or potentially DH once Joe Mauer is gone, though neither have the speed to play CF which makes them less than ideal 4th OF candidates. I tend to agree that Walker in particular gets traded as he's only got 2 options left, one of which will most assuredly be used come 2017, because like it or not, he hasn't been that good this year. Yeah, he hits home runs, but if you look at the rest of his peripherals, they aren't exactly sexy. You do have a point about repeating a level, hopefully, he figures things out a bit during his second go around in AAA, but the issue right now is BB and Ks. He's been a bit better there this year, so perhaps he is figuring it out. If he does, he's a beast.
