Well that was unexpected.
Morneau was eighth in the AL in OPS - second on his own team, behind Mauer, who's a catcher - 18th in OBP, 13th in EqA, and fourth in WPA.
Even Derek Jeter was better. Morneau's a fine defensive first baseman, but that doesn't come close to making up the ground between himself and the cream of the crop.
