I feel for Hiura, being sent down while he's been hitting had to suck. The 3-catcher thing is a roster albatross. Let's not forget, this organization has put a premium on run prevention, and it's been successful. That's why Davis is still here--it's a premium position where defensively there would be a big dropoff from him to the other current options. That's a large part of the problem with how they view Hiura. He has some versatility, but there isn't a spot on the field you can put him where you don't hold your breath. Very few teams do the "primary DH" thing like you used to see in the 70s, so that (along with a sub-par arm & the K's) will probably, sooner or later, spell the end for him here.
I guess you could trace this whole roster mess to Severino getting suspended & the organization feeling they needed to pick up Caratini. But it wasn't like trusting Alex Jackson to be the backup for a week or two ,It was an 80 game thing. It's certainly caused more problems than I envisioned.
