After the season Jake had last year, I don't understand this take at all...
Black hasn't been able to beat out Bauers (even the previous year's poorer version). Jake continues to improve, is a good defensive 1B, a good PH... Yet, you want to go back to scrap heap pickings?
Unless he really breaks out next year, I'd bet this is his last year (doing a second year of arbitration for a then 31yo backup 1B that gains less than 1.0 WAR is unlikely). But I don't think we will find a cheaper LH 1B that will outhit Jake this year either.
