I'm the original poster. Please assume that the BR going to first was running in a location where he normally would be called for interference. In the example given, can you call interference on the catcher when he doesn't have a play on the runner?

15u travel. Official BB Rules. Situation: First base occupied at time of pitch, less than 2 outs R1 stealing, third strike is dropped, BR runs to first (though he was out because first was occupied at time of pitch). Catcher throws to first. As BR nears first base--fully in the base line, not in the running lane-- catcher's throw bounces off the back of BR's helmet and bounces down the RF line. Play continues, as R1 crosses the plate ahead of a throw home. Umpires called the BR out (easy call) and returned R1 to second base (head-scratcher). Right call?
