Something we have to keep in mind with Tork is that he's still only 22 years old and, in the grand scheme of things, we can conclude from what we have seen that they rushed him too fast and, because of it, it may have impacted his growth as a hitter.
I'll freely admit that, along with most of the fanbase, I thought he should make the Opening Day Roster, but clearly that wasn't the case.
I do think he can be fixed though (like others, I don't have much trust in the org, but in general, his problems seem fixable), but if he's making mechanical changes to his swing, it stands to reason that it may take a little time and may not yield desired results 19 ABs after being sent down.
