The AL continues to dominate interleague play

The final interleague game of 2012 ended when Nick Swisher caught the last out of last night’s Yankees-Mets game. That brought the tally to 142 wins for the American League, 110 for the National League. Put differently, that’s a .563 winning percentage for the junior circuit, or a 91-win pace over the course of a 162-game season.

Ben Lindbergh of Baseball Prospectus has the numbers for interleague play since its inception, and they’re pretty ugly for the NL. The AL has won the series for nine straight years and, overall, have won at a .525 clip, going 2079-1883.

No one gets a prize for it or anything, but it is pretty telling regarding the relative strengths of the two leagues.
