I personally always wondered why the Phillies hired a Latin American scouting genius to run domestic scouting. Talent is talent, but the connections, network and the nature of the department that you're running is totally different. He did have considerable domestic experience with the Reds before that, granted, but at that point he was just a scout.
I don't think Almaraz had a chance to truly succeed, personally. As bad as Wolever was, he was also the fall guy for a spiraling front office. When Almaraz was hired, did anything really change in the scouting department overall? Was he given more resources, different personnel, an opportunity to install a new philosophy? Not really, as far as I can tell. And those first two drafts are perceived as the worst ones. It was only after Klentak got his first year under him that big changes (including at the Assistant GM level) were made. The approach changed too.
I think you actually do have to wonder if Sal will be next (even if it's not for another year). As I've said, the overhaul has moved a bit slowly for my taste, but it has certainly been comprehensive. All of the scouting and development stuff is being run by the Assistant GM Minniti (whereas, as I've noted before, past scouting and development bosses were themselves Assistant GMs) and this is only his second season on the job (he was a consultant or whatever the year before that).
If they promote his assistant that doesn't strike me as a bad thing and if they go looking for an outside hire that's probably fine too.
