In some lower leagues, school and summer ball, the DH can bat for any one of the field-position players, typically because or when the pitcher that day is one of the better ball payers on the team.

Then, there are kids leagues that have an "extra hitter" or where everyone bats, even if not playing the field.

Thank you for the detailled information !
