Comment includes this: “Rich sell: The simple solution for a revised IFR is in effect on a trial basis for 2021. It is a simple de-facto approach- when an IFR situation goes un-called- it is still allowed to play out to its conclusion and after review, the offensive team (if not for a tag up or running error) has the option of taking the Result, or, the automatic one out. This maintains the intent of the IFR, without advantaging the defense unduly. I proposed a similar revision in 1986 by letters to Dr. BROWN, and Mr. Uberoth; and, also to the Little League. But for the past 34 years I cringe at the IFR calls, especially in the Little League“
