Morel's defense certainly hasn't been pretty, but it also hasn't been the deciding factor in any game that I can recall. I'm ok with continuing to run him out there and maybe with consistent playing time things will eventually click. I think it's still too early to give up on the experiment and, if you're going to do it, it needs to be all in. Having him split time between 3B and DH probably doesn't accomplish a whole lot. I see it as trying to play a bit of the long game - recognizing that playing Morel at 3B might not be the absolute best lineup they can put on the field TODAY, but that it could lead to much better things in the future if he somehow does develop into an adequate fielder.
