What occurs when B4 is intentionally walked after B3 missed first base?

When a player misses first base, that base running infraction can be appealed by the defensive team. However, in the scenario where B4 is intentionally walked after B3 has missed first base, the situation complicates things. The act of intentionally walking B4 does not alter the status of B3 regarding their missed base.

In this context, the rules of baseball state that once B4 is intentionally walked, they are granted first base. However, B3's missed base is still subject to appeal but will not be acted on just because B4 is now on base. If B4 is walked and B3 is still on the base path, B3's status regarding the missed base cannot be appealed during that play. The defensive team would need to appeal the missed base separately at a later time, which implies that B3's missed base does not get affected by the intentional walk of B4 in the immediate play.

Therefore, the correct option emphasizes that while an appeal can potentially be made later regarding B3's infraction, it cannot be pursued solely because B4 has been walked. This highlights the notion that actions taken regarding one base runner do not negate or alter the situation of another runner who has possibly committed a base-running error
