Perhaps he has tried, but that is just not the type of hitter he is or can be. Perception is one thing, actuality is another. Sometimes they are the same, but unless you know for sure, and I suspect you don't, then I think your dislike is misplaced. If your perception is true, then it's still up to the manager to bat him in the appropriate place, and that's not what happens. If he won't or can't adjust, then the manager is wrong to continue batting him there. Period. And I think your dislike of Joe for that is still misplaced, with all due respect.
