We have four starters and no one prepared in AAA to step in to a starting role. Some of this is injuries but the other reason is they have turned the majority of the staff in St. Paul into bulk relievers. So they are not prepared from either a pitch count or facing a lineup multiple times to be starters. So bring up two of those guys to replace Ober and run your bullpen short.
Even with injuries you have to have guys in roles prepared to come up and help out the team. They may not have much success, but you can't run a bullpen game every 5th day.
They really need someone to come in and be a senior advisor to Zoll, I don't think he is up to the task of being the top baseball voice in an organization. And every day he flounders sets this team back even further.
Last thought, they really need to consider extending Jeffers, hopefully he would agree to it. Do you really want to see Caratini behind the plate for 100 games next year.
