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: Libero

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 – Libero - Listen

In volleyball, a libero is a defensive player who plays in the back row. It’s a fairly new position, as it was introduced in 1998 – and the libero plays by some unique rules:

► The libero wears a different color jersey from the rest of the team – so they are easily identifiable. Only one libero can be designated for each set of a match.

► The libero can serve, but can't perform an overhead set in front of the attack line, or complete an attack if the ball is above the net.

► The libero is never allowed to rotate to the front line.

► The libero is the first line of defense, often passing to the setter and covering open spaces.

► The libero can be replaced without restriction – but in the event of an injury, can only be replaced by the player the libero originally replaced.
