Beginning with the 2016 season in prep baseball, umpires will be required to issue a warning to coaches before restricting them to the dugout or ejecting them as part of a new penalty progression to promote preventative officiating.
The rule change was approved the by the rules commiitte of the National Federation of State High School Assns.
Previoulsy, issuing a warning to an offending coach was optional. Coaches can still be ejected on a first offense if it is deemed major.
Also part of the modification to Rule 3-3-1 is coaches who receive a written warning will be restricted to the bench for the rest of the game.
