Coach's Visit

[SanDiegoSteve]

The official interpretation is the same in OBR as the FED interp:

FED: (Edited) The coach may stand with his pitcher at the mound between half innings. If his presence creates a delay: PENALTY: The umpire "may" charge a conference. (3.4.1h and 6-2-2c Exception)

OBR Penalty: (Deary) If such a "conference" delays the game: Following the first delay, the umpire should warn the coach that on the next delay he will be charged with a trip to the mound. A team must be warned one per game before the penalty is invoked.

So, it seems to me that in FED, it isn't a mandatory trip for delay, but is optional, while in OBR, a warning has to be given first.
