JWC1022 posted:The key phrase here is; "In establishing the validity of the tag, the fielder shall hold the ball long enough to prove that he has complete control of the ball. If the fielder has made a tag and drops the ball while in the act of making a throw following the tag, the tag shall be adjudged to have been made." Another way of putting it is that the release of the ball after a tag must be "voluntary and intentional."
That's OBR, and that's not another way of putting it. Voluntary release is not required by the prevailing logic (as of today.)
