Our organization has instituted a new courtesy runner rule, allowing a coach to elect to use a courtesy runner for a pitcher or catcher at any time (courtesy runner must be the last player to make an out while at bat). FYI, this league uses continous batting order, free substitution in the field, but pitchers may not go back on the mound once removed. In the application of this, does it have to be the pitcher or catcher that was on the field for the previous half inning, for the upcoming half inning, or any combination that a coach feels is to his advantage.
For instance, Johnny is the starting pitcher. Bottom of the 5th Johnny draws a walk, coach sends in a courtesy runner for Johnny, then Jimmy comes out to pitch the 6th inning. Maybe coach was bending this rule to his advantage, maybe Johnny told coach in between inning that his arm hurt, either case is plausible. Should this be allowed?
ALSO, am I correct in assuming that just because a coach announces that he's sending in a courtesy runner that the ball is still alive and in play until an umpire anounces "time out"? If so, which runner should be tagged to record an out, the one who's leaving the field or the one who's coming on the field?
Should an umpire automatically call "time" when a coach announces a courtesy runner, or must the coach specifically request time out?
