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 – Base Runner Interference - Listen

Let’s head to the softball diamond today for a “You Make the Call," and how to score the play in the book.

We’ve got a runner on second with one out when the batter hits a grounder in the hole between short and third. The baserunner on second interferes with the shortstop attempting to make a play on the ball. 

What’s the call? What happens to both the runner and batter?

The runner on second is out for interference. And the batter is awarded first base. There are now two outs with a runner on first.

In the scorebook, the batter is credited with a fielder’s choice, not a base hit. But if the interference is ruled intentional, both runner and batter are out.

Be the Referee: Volleyball Libero Uniforms

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 – Volleyball Libero Uniforms - Listen

Before the match begins, a volleyball team takes the court wearing super-stylish, brand-new jerseys. The libero is in a bright neon top, but two other teammates also have the same neon sleeves.

At first glance, it looks like multiple liberos are on the floor. As the referee, you must check carefully: Under current NFHS uniform rules, the libero’s jersey must clearly contrast from all other teammates in color, design, and trim.

Accessories like sleeves or leggings are permitted, but they cannot confuse the identification of the libero. In this case, because the libero’s jersey color is the same as teammates’ sleeve color, the contrast is not sufficient, and the coach must correct it before play begins.

This ensures quick identification for substitutions, scoring, and libero actions.
