Major League Baseball (MLB) should change its name to Major Baseball League (MBL). Maybe I'll do it for them. Ladies and Gentlemen, now introducing the already existing Major Baseball League with its American and National conferences! Get used to it.
Much better. Now when some jerk like Cole Hamels of the Philadelphia Phillies takes it upon himself to hit a rookie like Bryce Harper of the Washington Nationals with a pitch he can accompany his cowardly act with a paraphrase of the line used for decades by players in the National Football League (NFL): "Welcome to the Major Baseball League".
In case it is not obvious enough the intent of this name change is to drive home the point yet again that the old American and National Leagues merged into one league known as Major. See:
