Below is this week's segment - Slide Rule - Listen

Recently there’s been a lot of conversation and discussion about Major League Baseball’s new slide rule – both at second base, as well as some of the new collision rules that are in effect around home plate.

For many years at the high school level, both baseball and softball playing rules have been ahead of the curve in keeping players safe.

In both high school baseball and softball, when runners do elect to slide, they must slide directly into the base on a force play. On those plays at the plate, runners must do everything they can do to avoid a collision with the catcher; by either making a legal slide, giving themselves up, or moving in a way to make those collisions at home plate a thing of the past.

Be the Referee: Illegal Substitution/Participation

Below is this week's segment – Illegal Substitution/Participation - Listen

We’re on the football field this week with 23 players.

Twenty-three is one too many; there should only be 22 on the field at once – 11 on offense, 11 on defense.

But on this play, the offense had a 12th player lined up on the field.

What’s the call?

It depends on when the penalty is spotted.

If the officials catch it before the play is run, that’s an illegal substitution and a 5-yard penalty.

But if the ball is snapped and a play is run with 12 on the field – and the 12th player is not attempting to get off the field – then it’s illegal participation and a 15-yard penalty. It’s also a 15-yard penalty if the offense uses a substitution to create a deception.
