What ruling follows when F2 obstructs B4 before the batter can become a batter-runner?

In this scenario, when F2 (the catcher) obstructs B4 (the batter) before the batter can become a batter-runner, it is recognized as obstruction. The rule surrounding obstruction is meant to protect the batter's rights to safely reach base without interference.

When F2 obstructs the batter, the appropriate ruling is to award the batter first base, as they were denied an opportunity to become a batter-runner due to the obstruction. If there are any runners on base at the time of the obstruction, the rules state that they could also be granted advancement based on their situation.

The presence of other runners at the time of the obstruction indicates that they could potentially also benefit from this ruling—if it affects their ability to advance safely. In this case, the runner may also score if the rule permits, depending on their circumstance at the time of the obstruction.

By awarding B4 first base, the intent is to rectify the situation caused by the interference, ensuring that play continues fairly and that the batter has a chance to complete the action of reaching base safely.
