I'd say that's overstating it. I don't hate it. It leaves me a little scared, yes, but I'm OK with that. For all of Heyward's issues he's still a plus defender. Zobrist is not, and his good last 3 weeks aside, I'd rather see him on the bench than Heyward, especially facing a pitcher that has the ability to shut us down. It seems like you're just glossing over/completely ignoring the fact that Zobrist is a much, much better hitter, especially vs. LHP.
