2-runners....1 base

[DG]

The rules stated are not in conflict. The following runner is out when tagged only when he is not forced. Otherwise the runner already on the base has posssession. In example given, force is in effect, since ball was not caught in left field.

The reason we have an infield fly rule, to call a batter out for inevevitable action, is to prevent the defense from an unfair advantage, ie a double play. Consider a major league infielder (or little league infielder), who would be allowed to intentionally let a routine fly ball to fall to the ground. A double play would be inevitable. We are not making the infield fly ruling just because the catch is imminent, to speed the game along, but to protect the offense from an action that has been deemed to be innappropriate by the baseball rules makers.

Now, on a separate subject you mention, I would have issues with a partner who overrules my call "on the spot", without any discussion with me. I have no problem with a partner who has information about a play and after discussion I have the opportunity to change my call. But a partner who reverses me without discussion is a poor partner that I will need to have a serious post game discussion with.
