If B1 does not reach first base before time for the next pitch, what is the ruling?

When considering the scenario where B1 does not reach first base before the time for the next pitch expires, the appropriate ruling is that B1 is declared out for not attempting to reach first. This is based on the principle that a player must actively attempt to advance to the next base following a hit or a situation where they are entitled to run. Failing to make that attempt before the next pitch indicates a lack of engagement with the play, and thus the player is penalized by being declared out.

In this case, the other options do not accurately reflect the rules governing this situation. Awarding first base would imply that the player did enough to warrant such an action, which contradicts the premise that they did not reach the base in time. Calling time and ceasing the play would not address the player's lack of action either. Finally, requiring an appeal is unnecessary here, as the player's failure to run is an automatic ruling rather than something needing to be challenged.
