What if MLB never expanded? This league took that question and ran with it, starting in 1961 and now well into the 1990s. We've got 16 teams in divisions of 4 playing in their pre-1960 ballparks. Two openings for 1994...the Braves and the Indians (rosters below). Pretty standard progressive rules--no AAA or DH, draft order is reverse order of finish at Game 162.
