[Bandit]

In summary.
NSA Courtesy runner.
A) Can be last out.
B) If last out was the pitcher or catcher you can go back one more out
C) If you have eligible subs they can courtesy run and not affect their substitution privileges.

QUESTION….Can they substitute in the same ½ inning they courtesy run?

D) If you have a player sitting on the bench and she has “used up” her substitution privileges…..been in the game twice…..she can still be used as a courtesy runner.
E) If a player currently in the batting order is used as a courtesy runner and her turn at bat returns while she is on base the coach may:
1) Courtesy runner remains on base, and loses turn at bat with no penalty, and next batter is batter following that position.
2) Courtesy runner may be replaced on base by the player being run for, and then taking their turn at bat.
F) No player may be used as courtesy runner twice in the same inning. If the situation arises that a player HAS already run as a courtesy runner in the same inning you “go back” one more “out” to obtain a legal courtesy runner.

Have I missed anything?
