That’s the way it’s working in both the American and National Leagues to date this year:
AL East vs. AL Central: 37-20 – .649
AL East vs. AL West: 29-22 – .568
AL West vs. AL Central: 33-29 – .532
NL East vs. NL Central: 45-33 – .577
NL East vs. NL West: 34-25 – .576
NL West vs. NL Central: 25-23 – .521
I doubt it’ll be a revelation to anyone here that the AL East has been the game’s strongest division thus far. Including the 8-7 interleague record, it has a .602 winning percentage in interdivision games.
