Eight divisions with four teams each, which is a huge shift from today's six divisions with five teams. The American League gets condensed (confined to the heavily populated East Coast out to the Great Lakes region), while the National League stretches out for far more square mileage.

Baseball insiders have whispered about the possibility of regional-based realignment for a few years. MLB commissioner Rob Mandred was asked directly about it on Sunday night during an ESPN broadcast, and didn’t shy away from his next bold rules change.

Adding two new teams would allow MLB to even the two leagues out at 16 teams apiece, making daily interleague play no longer necessary. It also creates the opportunity for realignment. Manfred hinted at the possibility of wholesale realignment based on geography during an appearance in ESPN's Sunday Night Baseball booth this past weekend.
