Obstruction/confusion

OBR, no; Fed, depends

If the batter-runner rounding first base is obstructed and the umpire adjudges that he was not attempting to acquire second base (simply rounding does not indicate attempt to advance to second) and makes it safely back to first base, then the obstruction is ignored. Refer to the 2006 NFHS rule change in 8-3-2.

However, if the batter-runner is rounding first base, is obstructed and does NOT make it back to first base safely, then obstruction is enforced and a minimum one advance base is awarded. NFHS 8-3-2.
