It depended on the rule code you were using during the game.....
If it was NFHS or NCAA rules, then you have verbal interference....
rule cite: NFHS 2-21-1a
"interference is any act (physical, visual or verbal that impedes, hinders or confuses the defense"
In OBR (which most summer leagues use) this is not interference..
In OBR it is not interference if the intent to interfere is solely verbal....meaning, to me, that at the big boy level, you are expected to know your own teammates voices....
I have known umpires to eject players for unsportsmanlike conduct for that type of play....
So, if NFHS or NCAA, you have interference and an out, in OBR you simply have a foul ball......
Hope this helps.
