If Joey could increase his Z-swing percentage by 5 percent, at the expense of his O-swing percentage going up 2 percent.. I think that would be worth it.
Note, I realize that increasing the Z-swing is going to also probably increase the O-swing.
I guess I don't see the correlation between swinging at any pitch within the strike zone and increased run production. Considering the distinction is not made between "pitcher's strikes" and "cookies". If he were regularly passing up "cookies" then I would have more of a problem. I don't have a problem with his approach at all.
