The designated hitter in the American League has prolonged the careers of several sluggers over the years. Albert Pujols recently signed a 10-year contract with the Angels and will play first base and DH.
The deal makes much more sense for an American League team that can use Pujols as a DH when his age and athleticism decline. Pujols will be 41 years old, if he plays for the life of the contract. As he gets older, we can expect to see more instances of him being a DH rather than playing in the field.
It is my personal belief that there should be one set of rules for all of Major League Baseball. The strategy of baseball is greatly diminished with the DH. Its time has passed, and as a baseball purist, I feel that the DH minimizes the strategic decisions a manager must make over the course of a ball game.
Having two sets of rules makes no sense, but since baseball does not seem ready to make any changes, we are probably stuck with it for awhile.
Let's take a look at some of the National League sluggers that would make good DH's. In order to be considered, a player must be an average or below-average defensive player.
