I have always wished for a Great Lakes division. With MLB moving away from the AL-NL divide with season long interleague games we can move to geographical rivalries divisions. This is my proposed realignment: I would have liked to add Cleveland to the Great Lakes division but it makes it harder to keep up the Chicago rivalry and the Battle of Ohio. Playoffs: 6 Division winners + 4 best records play 2 games (7 vs. 10 and 8 vs. 9) to determine the 8 matchups. EAST : Boston Red Sox, New York Yankees, New York Mets, Philadelphia Phillies, Pittsburgh Pirates ATLANTIC: Baltimore Orioles, Washington Nationals, Atlanta Braves, Tampa Bay Rays, Miami Marlins GREAT LAKES: Toronto Blue Jays, Detroit Tigers, Milwaukee Brewers, Chicago Cubs, Chicago White Sox MIDWEST: St. Louis Cardinals, Kansas City Royals, Cincinnati Reds, Cleveland Indians, Minnesota Twins SOUTHWEST: Texas Rangers, Houston Astros, Colorado Rockies, Arizona Diamondbacks, San Diego Padres PACIFIC: Los Angeles Dodgers, Los Angeles Angels, San Francisco Giants, Oakland Athletics, Seattle Mariners
