Pull Hitter

From MLB Power Pros Wiki

The blue ability, Pull Hitter, is a skill that is tough to explain why you would want it. The skill Push Hitter does the opposite of this ability, because you normally hit to the same side you bat. Well, this skill makes the fact that you hit to the same side even more pronounced, so I suppose if you were a power hitter and swung for the fence every time, this might assist your ability to hit a homer on that side more often. Probably useful if you are the Red Sox and want your batters to swing for right field, so you can avoid the Green Monster.
