Be the Referee: Pitcher Arm Care

June 8, 2015

This week, MHSAA assistant director Mark Uyl explains how the 30 out-limit rule works to keep baseball pitchers' arms healthy.

Be The Referee is a series of short messages designed to help educate people on the rules of different sports, to help them better understand the art of officiating, and to recruit officials.

Below is this week's segment - Pitcher Arm Care - Listen

Health and safety continues to be the major focus of the MHSAA. One rule that is geared directly to player safety is our baseball pitching limitation rule of 30 outs.

The 30-out rule limits the number of innings, or outs, that a pitcher can throw in both a given day as well as over a period within a week. 

We want to make sure that high school coaches are not overusing their pitchers; that they are finding that safe area, to where arms have the ability to recover after a player has pitched a certain number of outs, allowing the body to recover so that player can have a safe and enjoyable season.

Be the Referee: Field Hockey Substitution

Be The Referee is a series of short messages designed to help educate people on the rules of different sports, to help them better understand the art of officiating, and to recruit officials.

Below is this week's segment – Field Hockey Substitution - Listen

We are on the pitch today for a field hockey “You Make the Call.”

During the execution of a penalty corner, the defending goalkeeper is struck on the hand and cannot continue. How is play resumed?

  • Allow a properly equipped goalkeeper to substitute.
  • Disallow any substitution; the injured goalkeeper must remain in the game.
  • The defending team shall forfeit.

If you said to allow the substitution, you are correct. Under Rule 4-4-3, a goalkeeper substitution is permitted during a penalty corner in the event of injury or suspension. Once the new goalkeeper is ready, resume play with the continuation of the penalty corner.

Field players, however, may not substitute until the penalty corner has been completed. This ensures proper game flow while prioritizing player safety.
