This can be viewed as a list of the pitchers with the filthiest/most confusing stuff and a list of the most aggressive hitters, or just the most wreckless ones. The pitchers should be of no surprise, as these are pretty much the cream of the crop arms in baseball. The list of hitters is fairly mixed, with the biggest surprise being that perennial strikeout "king" Adam Dunn is nowhere to be found. But to no surprise, the list of hitters is made up primarily of some pretty decent Home Run hitters.
