I think this would be the rule that covers it:
Rule 3 Section 3
b. At the time of the pitch, the base coach may not be closer to the foul line
than the inside edge of the coaches' box and no closer to home plate than
the front edge of the box (see also Rule 2-6, Base Coach). A coach may leave
the coach's box to signal the player to slide or advance or return to a base as
long as the individual does not interfere with the play.
c. Base coaches may address only their team members.
d. A base coach may not use language that will reflect negatively upon the
players, umpires or spectators.
PENALTY for b., c. and d.-Ejection from game after a warning
