If a 2020 Major League Baseball season is played, then extra innings could look significantly different.
Instead of the traditional extra innings format, the MLB is considering placing a runner on second to start each inning. This has been experimented with in the minor leagues, and has received mixed feedback. What they do in the minors is use the person who was the last out in the previous inning as the runner. Teams aren’t able to select runners unless they make a substitution.
Additionally, the league is considering instituting ties this season. If the game is tied after a certain number of extra innings, it may go down in the scorebook as a tie.
