Oakland’s system is slowly on the way back up after bottoming out during their last run of contention, with newfound depth in right-handed pitching, especially six-foot right-handers, so maybe that’s their new inefficiency. They’re lighter on potential impact position players, but what they do have in that department is either in the middle of the diamond or the occasional plus defender on a corner.
