I haven't really followed the Halos that long but Soc seems like he's past his shelf life. (like an Arsene Wenger).
The problem I see is that Ohtani has bought Soc 1-2 years. I don't think they will fire him since Soc was part of the package that attracted Ohtani to Anaheim. It would be too big a change to someone (Ohtani) who is already adjusting to a new country, culture, peoples and baseball league. And they wouldn't want Ohtani to become disgruntled if his favorite and familiar manager is fired.
