| 4-1 |
There is no upper limit on the number of active players. |
| 4-2 |
The ten defensive positions that are allowed can be filled only by
active players and can be interchanged amongst these players at any time. |
| 4-3 |
A non-active player can be activated either by creating a new slot
in the lineup or by substituting for an active player. However, a player
who had been previously deactivated can be reactivated only if two complete
innings have elapsed and only if at least nine other at-bats are between
his previous at-bat and his coming at-bat. |
| 4-4 |
If a player is deactivated without a substitute his slot in the lineup
becomes vacant. The manager must announce when this occurs, or the rules
for batting out of order will be applied when the turn at-bat of the deactivated
player is skipped. |
| 4-6 |
The home team cannot have a smaller number of active players in the
bottom half of an inning than it had defensive positions in the top half
of the inning. Result: The rules for batting out of order will be applied
when the turn at-bat of the deactivated player is skipped. |
| 4-7 |
The visiting team cannot fill a larger number of defensive positions
than it had active players in the top half of the inning. Exception: Any
player arriving late at the field may be activated and inserted into the
game immediately. |
| 4-8 |
A "courtesy catcher" will be provided if requested by a team having
less than 10 defensive players. The only function of the courtesy catcher
is to protect the umpire (i.e., return dead balls to the pitcher). His
presence will be treated as having no effect on a play unless he intentionally
interferes with a defensive player. The courtesy catcher is required only
during play and is not required to warm up the pitcher. |
| 4-9 |
A "courtesy runner" is an active player who replaces a base-runner.
If the original base-runner is to remain an active player, he can be replaced
by a courtesy runner only with the approval of the opposing team. If however
he is to be deactivated without a substitute, no approval is required.
In all cases, courtesy runners are to be chosen by the opposing team. If
a courtesy runner is on base when it is his turn to bat, an alternate courtesy
runner must be chosen to replace him on base. |
| 4-10 |
A delay to the game starting time not exceeding 5 minutes will occur
if requested by a team having less than 9 players. If after this delay,
or at any time after the game has begun, a team has less than 6 players,
it will forfeit the game. The score of a forfeited game can be chosen by
the non-forfeiting manager to be the score at the time of the forfeit,
or 7-0, or 7-7. |
