Interleague play is weird this year. The outcome is similar, but how they got there is weird.
In the four game series where teams play their "rival" 2 home and 2 road, the AL is absolutely crushing teams: 38-18
Every other 2- and 3- game series total is even: 97-97
Total:
AL 135
NL 115
With the DH (home), AL teams are 64-61.
Without the DH (road), AL teams are 71-54.
By Division:
AL East 50-37
AL Cent 45-38
AL West 40-40
NL East 39-40
NL Cent 41-39
NL West 35-56
The NL West is terrible in interleague play, but when they play the NL East or Central, they're about .500.
