Infield fly rule

[Ernie Marshall]

Under OBR you do have to call it, and I agree with other posts that you should have made a more definite call. If the runners advanced under confusion (i.e., was INF called or not) I think you should have allowed runners back to bases with the INF out only. If the runners advanced out of clear intent to take a base, then they advanced at their own peril and double play should stand.

Best rule of thumb. Step forward with finger in air and loudly call "Infield fly rule IF FAIR". Repeat call if you see confusion. Also, you should go over this, especially at this level, prior to game.
