Infield Fly Rule Revisited

[Bunky]

I was researching the infield fly rule and found that there are differences in the rule for obr and Fed rule. Now the Fed rules don't make sense. Under obr when the umps do not call infield fly rule and the ball is dropped, then the defense can only get 1 out. Under Fed rules, If the umps do not call infield fly, then the fielder can drop the ball and get a double play, which is what the rule is supposed to prevent --isn't it? Now, knowing that the umps don't have to call it and the coaches and players must realize infield fly rule situation---Then why is is a judgement call on wether or not the fielder is making a routine play. There is no way I'm going to send my runners if it's a pop fly, even if its a flare and the defense has to make some effort to get the ball. Boom--- ball is not caught and the defense turns two. I Feel the UMPS should have to call it loud and clear or it should be a dead ball if dropped... What about it.......?????
