Playing a grand slam tournament. Other teams coach made 3 mount visits to same pitcher and wasn’t required to remove pitcher. Rule has always been pitcher must be removed on third mound visit. Umpires were at a disagreement. Called to the upper people and they stated that rules were different for THIS tournament. It honestly seemed as the other coach was doing visit to kill time. No different rules were given to coaches or umpires. Is there a clear definition to what the rule is for grand slam tournaments. Do rules changes for specific tournaments? There were only 7 teams playing in this 12U A tournament. If rules are changed what should the procedure be seeing teams were not made aware of the change?
