My chapter made us aware of this UIL restriction but the enforcement would not be ours. We don't have access to the pitching records (we are there for most DHs but we don't keep track of the pitchers). We were told to refer this to the district chair (regular season) if it was brought up.
The cell phone call probably saved a much worse mess and the ump who took it was probably clueless but made the right decision.
SAump you sound like a fan.

Very little pitching restrictions in TX but this one is correct. Once you cool down the micro tears set in and hard throwing after that causes more damage. I even hate to see a removed F1 sent to RF where the possibility of a hard throw from a cold used arm might be possible.
