When I make a sub for the LF (or any position) with a player that was initially non-batting in the roster, does he automatically get placed in the batting order or do I have to do that manually?

Offensive and defensive subs are made separately.

Offensive and defensive subs are two separate substitutions. (Many users have lineups that bat everyone.) You can enter both subs at the same time by hiting the offense/defense button on the substitution screen.

Thank you.
