Adopted 2022 - DH allowed for any position player but must follow same rules as if you were DH'ing for the pitcher.

Adopted 2022 - Teams allowed to Bat any number of players from their bench. Announce it at the plate meeting. If any others are on the bench then they can be brought in but then must follow normal changes for those moves. i.e. Team has 14 players, batting lineup says 11 batting then those 11 batting can go in and out defensivly for each other throughout the game, but if the 3 not batting come in then the person being removed is "out of the game" and cannot be re-entered. 

Adopted 2023 - Ohtani DH Rule - Pitcher can be listed as P/DH on the batting lineup and remain in the DH spot for the incoming relief pitcher.
