Guys like Dozier and Florimon know perfectly well how to swing a bat, but they need to learn situational hitting, which is more complicated than simply knowing the situation. First, you have to know the situation, which includes the score, the pitcher, how many outs, who's on base, where, etc. Second, you have to know how to read physical cues from the pitcher, the fielders, etc. Third, you have to understand how the first two things alter the likelihood of seeing particular pitches in particular locations. Fourth, you have to learn to actively bluff the pitcher with false cues, like acting frustrated, muttering to yourself, waving the bat, or not, etc. Knowing all these things is how a batter applies pressure to the pitcher, which is facet of applying pressure in general to the opposition. Fifth, you have to believe you can control the game. Very few players are able to internalize that attitude. The ones that do...control the game.
