No, Zeuch has literally been terrible. He has been exactly as terrible as most of us expected, arguably even worse. The defensive miscues are a distraction from the fact that he's not striking anyone out, giving up a ton of hard hit contact and having runners on base all the time. The "stat book" doesn't care about what the defense does because all it matters is that balls are being put into play in the first place; and importantly, they're not being put into play weakly so we can't say he's been unlucky. If Palacios catches that then Zeuch was lucky that allowing a 325 flyball didn't result in damage, same with any line drive that's hit off him and happens to find a glove.
