Looking at the standings this morning, it would seem the American League has been beating up on the National League.
I'm sure someone could find the exact numbers, but I'm guessing on this based on the fact that there are more teams under .500 on the Senior circuit.
In fact as of today there would be two teams in the NL under .500 making the playoffs.
To be fair, if the GM' s of the NL teams knew on the off season they'd be using the DH all year they might have constructed their rosters differently.
