American League Baseball is much because of the designated hitter tule. National League baseball is much more exciting because the picture hits and managers have to make more decisions.
The American League has one notable difference versus the rival National League, in that in modern times since 1973 it has had the designated hitter rule. Under the rule, a team may use a batter in its lineup who is not in the field defensively, replacing the pitcher in the batting order, compared to the old rule that made it mandatory for the pitcher to bat. In the last two decades, the season schedule has allowed occasional interleague play.
Major league baseball should abolish the designated hitter rule so both The National and American league play under the same rules.
