September is a pretty short, meaningless look, in many cases. Parmelee, etc. I'd rather have a larger sample to decide whether Anderson is a guy who can learn and adapt and succeed at the MLB level, or if I need to look elsewhere for the position in 2017. And I don't think either Anderson or Walker have MVP futures. But I don't think the logical conclusion from that is to potentially leave them in AAA forever until their game changes. Walker is easy, the Twins have plenty other OF/DH options to look at, so sure he stays in AAA. But Anderson? The White Sox have nothing at the spot, Anderson plays a position where a lack of offense can be tolerated under the right circumstances, etc. And as I said before, his game hasn't been changing in the minors. Maybe a little failure in MLB might give him a more focused plan on changing his game in a return trip to the minors. There is still plenty of time for the White Sox to make poor decisions around Anderson -- judge his MLB performance by the wrong stats or a small sample, run him out to fail for too long in MLB, fail to get a proper Plan B this winter, etc. But I don't think calling him up right now is necessarily a mistake, given his record.
