For some reason, Black reminds me of Jim Slaton from the 70's. Maybe a litle Joey Votto, too... 😉
While with the Mudhens, Hiura's K rate was 32%. Since being released and picked up by the Angels organization, his K rate is worse. It is 34% with Salt Lake.
Hiura seems like a nice guy. I'm not sure what happened during the pandemic, but it seems like he is either incapable of making the change, is not willing to make a change, or nobody is showing him how to make the change. Turang realized something needed to change and, on his own, took the initiative to get better. I believe Black will be much better with time. It is early.
