R1. B1 grounds to F6. R1 is forced out at 2B, but the relay throw is not in time at 1B. Next, retired R1 gets into a rundown between 2B and 3B and is tagged "out" again as B1 takes 2B. Ruling: In FED, B1 remains at 2B. In NCAA and OBR, B1 is out for R1's INT.

Section 274 of the 2006 BRD also notes, "NCAA: A retired runner my not continue to advance if such action 'hinders or impedes' the defense."

What does Carl use as his source for the NCAA and OBR rulings on this play (and the other you cited)?
