Posted a couple of weeks ago, but worth repeating and expanding, at least I think so.

Not just for this topic, but many people get confused because of ambiguous terminology in conversation, cases, even clinics.
A frequent example is the difference between player, lineup and batting order.

A player is a person (Erin, Cassidy, Elayna) with a uniform number (#18, #14, #7).

A position or designation is a function or sequence for game management, defined on a lineup, with last names of course.

All players participating are shown on the lineup. All players playing offense, i.e. batting, are shown in the batting order portion of the lineup.

A player (Erin #18) is only allowed one re-entry,
But multiple players (Cassidy #14, Elayna #7) can hold a position/designation (defense or offense) during a game.

For most rules:
the lineup includes the Flex but the batting order is only the players currently on offense.

For DH, EP, AP rules:
where EP, AP are used, those positions are also in the batting order. Where DH/DP is used, the DH position is also in the batting order, and the DP is there as a note and defensive position.


Oh, and courtesy runners are just that, a courtesy, not a substitution, not counted as in the game and can not be replaced by another CR. If the CR is replaced on the bases by a substitute, that substitute also replaces the pitcher or catcher the CR was running for. This comment ignores injury/shorthanded situations.
