Rule 8-2-6: A batter-runner who reaches first base safely and then overruns or overslides may immediately return without liability of being put out provided he does not attempt or feint an advance to second. A player who is awarded first base on a base on balls does not have this right.
If the BR is in jeopardy (where he normally would not be) then all other runners should be subject to the same enforcement. R1 is out after he passes 2B and is tagged (1/2” or 3’
).
