5.12 Calling “Time” and Dead Balls
(a) When an umpire suspends play, he shall call “Time.” At the umpire-in-chief’s call of “Play,” the suspension is lifted and play resumes. Between the call of “Time” and the call of “Play” the ball is dead.
(b) The ball becomes dead when an umpire calls “Time.” The umpire-in-chief shall call “Time:
(1) When in his judgment weather, darkness or similar conditions make immediate further play impossible;
(2) When light failure makes it difficult or impossible for the umpires to follow the play;
NOTE: A league may adopt its own regulations governing games interrupted by light failure.
(3) When an accident incapacitates a player or an umpire;
(A) If an accident to a runner is such as to prevent him from proceeding to a base to which he is entitled, as on a home run hit out of the playing field, or an award of one or more bases, a substitute runner shall be permitted to complete the play.
(4) When a manager requests “Time” for a substitution, or for a conference with one of his players.
(5) When the umpire wishes to examine the ball, to consult with either manager, or for any similar cause.
(6) When a fielder, after catching a fly ball, steps or falls into any out-of-play area. All other runners shall advance one base, without liability to be put out, from his last legally touched base at the time the fielder entered such out-of play area.
(7) When an umpire orders a player or any other person removed from the playing field.
(8) Except in the cases stated in paragraphs (2) and (3)(A) of this rule, no umpire shall call “Time” while a play is in progress.
After the ball is dead, play shall be resumed when the pitcher takes his place on the pitcher’s plate with a new ball or the same ball in his possession and the plate umpire calls “Play.” The plate umpire shall call “Play” as soon as the pitcher takes his place on his plate with the ball in his possession.
