Absolutely and seeing as how most youth pitchers go into the wind up rather than stay in the stretch with bases loaded, it takes longer for the ball to be released so the runner has a jump on the pitcher if he goes on 1st movement.

Heck, Coach Paul, I'm still trying to work out how a pitch that is already in the strike zone can hit a runner who is making a head-first slide before said runner touches the plate?

His knees are bent obviously...... ;^)

Extension...
 

So less than 2 strikes is a "strike call" and runner out?

Fed: No. You call the pitch and the ball is dead. Each runner except the batter is awarded one base. 8-3-1a.

(edited to remove completely incorrect response)

The pitch is either a strike or a ball. The runner from third is awarded home and all other runners advance one base. The batter remains at the plate with a ball or strike added to the count.

Bob, how is the runner out?

He's not. I apparently mis-read the question. I'll edit my response.
