They can’t bubble wrap them, but some of the arms need to have their innings watched.
I don’t think Keuchel makes sense as of now. But, let’s be honest, the Tigers have not had much luck with pitching health so far this season. They may be scraping around for pitching before the season is out.
I wouldn’t dump anyone from the 40 for him, but if injuries escalate and guys assumed to be back from the 60 aren’t before the end of the season, what do the Tigers do? I suppose they could just bring guys up from AAA, but keep in mind that the AAA seasons are extended to the end of September. Maybe they just promote from AA if they pull enough from AAA, but again, they’ll have workloads to monitor.
