My Conferences and divisions would look as follows: AL - Babe Ruth Conference: East Division: NYY, Bos, Bal, Tor Lakes Division: MN, Chisox, Cle, Det AL - Walter Johnson Conference Coastal Division: Anaheim, Oak, Sea, Portland Plains Division: Hou, Tex, KC, Colorado NL - Jackie Robinson Conference: Metro Division: NYM, Phil, Wash, Montreal Dixie Division: Miami, Atlanta, Cincinnati, Tampa NL - Cy Young Conference: Central Division: Cubs, Mil, St. L, Pitt West Division: LA, SF, SD, AZ 48 games played within your division (16 games x 3 teams) 48 games vs other division in conference (12 games x 4 teams) 48 games vs opposite conference (6 games x 8 teams) 12 games vs 1 division opposite league (3 games x 4 teams - alternate over 4 seasons) 156 games total Playoffs: Playoff teams, 4 division winners in each league, 2 non-division winners with next best record (not necessarily second place teams) in each conference, a total of 16 playoff teams, 8 in each league Round 1: Conference Semi-Finals - 2 division winners host (#1 record div winner vs #4 conf Wild Card) (#2 div winner vs #3 conf Wild Card); 3 game series Round 2: Conference Finals - Winners of semi final series, best record (division winner priority gets home field advantage), 5 game series Round 3: LCS, as currently laid out, 7 game series Round 4: WS, as currently laid out, 7 game series
