Sure, Wiemer's upside is higher, but what he is right now is borderline unplayable and there's a lot of risk with him.
Meanwhile, you've got Taylor giving you above average production on offense and defense.
Tyrone Taylor's value is actually rock solid. Been above average (100+ wRC+) hitter every season of his career with solid power numbers and above average defense everywhere in the OF. What you're seeing right now is a huge regression to the mean with how awful he started the year (due to not being fully recovered from his injury).
Wiemer is going to have to look like a major league hitter at some point.
I don't know what to say with Hiura anymore until he actually faces MLB pitching again.
Because I still could easily see him getting the call and striking out with his usual frequency to where it cancels out whatever power he shows. At the same time, there is some reason to believe that the changes he's made could be the difference.
We'll find out their intentions by Sept 1st.
He has a great arm and when the ball is in the zone good things tend to happen. Unfortunately, you never know where you're going to get a meltdown outing from Megill where he can't find the zone.
