Just when you thought a 2020 baseball season couldn’t look more bizarre, Major League Baseball and the players union are considering the possibility of having games end in a tie for the first time in the sport’s history, and at the very least, will change the format of extra innings.

The two sides agreed in their proposal this week, obtained by USA TODAY Sports, that they will adopt the minor-league rule in 2020 that every inning after the ninth will start with a runner on second base. In the postseason, games will revert back to traditional rules.

The union also wants to discuss with MLB the possibility of changing the substitution rules in extra innings, allowing players to re-enter the game among other possibilities.
