Zone rating (Keystone expected outs)
SeasonZoneBallsOuts vs. exp.
Too few balls in his zone.

The zone rating counts every ball hit to his part of the field while he played there, his club’s positioning included; Savant OAA uses his actual starting spot and is the better individual grade. They agree best in the outfield. See the model card.
