Is UC only valid for NFHS?

Penalties for various codes?

Sounds as if you would lean toward an UC or malicious contact call on the runner. If so, why would F3 get a free pass after continuously positioning themselves in the path of the runner? If you are going to eject the runner for the contact, why not also eject the fielder for UC for repeatedly and deliberately getting in the way of the runners.

NFHS malicious contact by the offense is always an out call and ejection, ASA has no provisions for an out call for UC. At the conclusion of play, call time, inform the coach the player has been ejected and they need a substitute to replace the runner.
