- Amended Rule 5.07(b) regarding warm-up pitches that a pitcher may
throw
2017
5.07(b) (8.03) Warm-Up Pitches
When a pitcher takes his position at the beginning of each inning,
or when he relieves another pitcher, he shall be permitted to pitch
not to exceed eight preparatory pitches to his catcher during which
play shall be suspended. A league by its own action may limit the
number of preparatory pitches to less than eight preparatory
pitches. Such preparatory pitches shall not consume more than one
minute of time. If a sudden emergency causes a pitcher to be summoned
into the game without any opportunity to warm up, the
umpire-in-chief shall allow him as many pitches as the umpire
deems necessary.

- Amended Rule 5.09(c)(1) Comment regarding a runner who takes a “flying
start” from behind a base when tagging up; namely, such violation is
now considered an appeal play
2017
Rule 5.09(c)(1) Comment (Rule 7.10(a) Comment): “Retouch,”
in this rule, means to tag up and start from a contact with the

flying start from a position in back of his base.

- Re-titled Rule 5.10(l) and amended Rule 5.10(l) Comment regarding

5.10(l) (8.06) Visits to the Mound←2018修改標題
Rule 5.10(l) Comment (Rule 8.06 Comment): If the manager or
coach goes to the catcher or infielder and that player then goes
to the mound or the pitcher comes to him at his position before
there is an intervening play (a pitch or other play) that will be
the same as the manager or coach going to the mound.
Any attempt to evade or circumvent this rule by the manager or
coach going to the catcher or an infielder and then that player
going to the mound to confer with the pitcher shall constitute a
trip to the mound.
If the coach goes to the mound and removes a pitcher and then
the manager goes to the mound to talk with the new pitcher,
that will constitute one trip to that new pitcher that inning.
A manager or coach shall not be considered to have concluded
his visit to the mound if he temporarily leaves the 18-foot circle
surrounding the pitcher’s rubber for purposes of notifying
the umpire that a double-switch or substitution is being made.
In a case where a manager has made his first trip to the mound
and then returns the second time to the mound in the same
inning with the same pitcher in the game and the same batter at
bat, after being warned by the umpire that he cannot return to
the mound, the manager shall be removed from the game and
the pitcher required to pitch to the batter until he is retired or
gets on base. After the batter is retired, or becomes a base runner,
then this pitcher must be removed from the game. The
manager should be notified that his pitcher will be removed
from the game after he pitches to one hitter, so he can have a
substitute pitcher warmed up.
The substitute pitcher will be allowed eight preparatory pitches
or more if in the umpire’s judgment circumstances justify.

- Established new Rule 5.10(m) limiting the number of mound visits per
game.
2017
無
2018
5.10(m) Limitation on the Number of Mound Visits Per Game
The following rule shall apply in Major League games. National
Association Leagues may adopt a rule providing for a different limitation
on the number of mound visits permitted in a game or no
limitation on the number of mound visits.
(1) Mound visits without a pitching change shall be limited
to six per team, per nine innings. For any extra-innings
played, each team shall be entitled to one additional nonpitching
change mound visit per inning.
(2) For purposes of this Rule 5.10(m), a manager or coach
trip to the mound to meet with the pitcher shall constitute
a visit. A player leaving his position to confer with the
pitcher, including a pitcher leaving the mound to confer
with another player, shall also constitute a visit, regardless
of where the visit occurs or the length of the visit,
except that the following shall not constitute visits:
(A) Discussions between pitchers and position player(s)
that occur between batters in the normal course of
play and do not require either the position player(s)
or the pitcher to relocate;
(B) Visits by position players to the mound to clean
spikes in rainy conditions;
(C) Visits to the mound due to an injury or potential
injury of the pitcher; and
(D) Visits to the mound after the announcement of an
offensive substitution.
(3) Cross Up in Signs. In the event a team has exhausted its
allotment of mound visits in a game (or extra inning) and
the home plate umpire determines that the catcher and
pitcher did not have a shared understanding of the location
or type of pitch that had been signaled by the catcher
(otherwise referred to as a “cross up”), the home plate
umpire may, upon request of the catcher, allow the
catcher to make a brief mound visit. However, any
mound visit resulting from a “cross up” prior to a team
exhausting its allotted number of visits shall count
against a team’s total number of allotted mound visits.
- Amended Rule 6.01(a)(5) Comment to clarify that a runner who is returning
to his last legally touched base after being put out is considered the
same as a runner who continues to advance after being put out relative to
interfering with a subsequent play
2017
Rule 6.01(a )(5) Comment (Rule 7.09(e) Comment): If the batter
or a runner continues to advance after he has been put out,
he shall not by that act alone be considered as confusing, hindering
or impeding the fielders.
2018
Rule 6.01(a )(5) Comment: If the batter or a runner continues to
advance or returns or attempts to return to his last legally touched
base after he has been put out, he shall not by that act alone be
considered as confusing, hindering or impeding the fielders.
- Amended Rule 8.02(c) to set limits on when a ball/strike count may be
corrected.
2017
8.02(c) If a decision is appealed, the umpire making the decision may
ask another umpire for information before making a final decision.
No umpire shall criticize, seek to reverse or interfere with
another umpire’s decision unless asked to do so by the umpire
making it. If the umpires consult after a play and change a call
that had been made, then they have the authority to take all
steps that they may deem necessary, in their discretion, to eliminate
the results and consequences of the earlier call that they
are reversing, including placing runners where they think those
runners would have been after the play, had the ultimate call
been made as the initial call, disregarding interference or
obstruction that may have occurred on the play; failures of runners
to tag up based upon the initial call on the field; runners
passing other runners or missing bases; etc., all in the discretion
of the umpires. No player, manager or coach shall be permitted
to argue the exercise of the umpires’ discretion in
resolving the play and any person so arguing shall be subject to
ejection.

missed ball-strike count shall not be permitted after a pitch is
thrown to a subsequent batter, or in the case of the final batter
of an inning or game, after all infielders of the defensive team
leave fair territory.
- Amended Definitions of Terms—Spectator Interference (“Interference,”
Part (d))—to include additional situations when Spectator Interference
may be invoked
2017
10.44(d) Spectator interference occurs when a spectator reaches out of
the stands and over the playing field, or goes on the playing
field, and (1) touches a live ball or (2) touches a player and hinders
an attempt to make a play on a live ball.
