Break down by division:
AL East: 4 teams (5 total appearances, 2 by the Yankees)
AL Central: 2 teams
AL West: 2 team
NL East: 3 Teams
NL Central: 3 Teams (5 total appearances, 2 each by Cubs and Cards)
NL West: 3 Teams
Surprisingly balanced! For the most part you get the presumed front runners of each division as well as appearances by a couple of random teams like Baltimore, Oakland and San Diego. I wonder what the ESPN and Fox schedules for the same time frame look like?
