In the situation where R1 slides directly into second base, how is that action ruled?

The ruling for R1 sliding directly into second base is considered legal because sliding is a permitted action when attempting to reach a base. In baseball, players are allowed to slide in order to avoid being tagged out or to reach the base safely. As long as R1's slide is done in a manner that does not violate the rules regarding interference or obstruction, the action is within the regulation play.

Sliding is a fundamental part of the game, designed to promote both athleticism and safety as players navigate the bases. If R1 slides directly into the base without making contact with the fielder in a way that impairs their ability to play the ball, it does not constitute interference and should not be ruled as obstruction.

This legal action promotes fair play and competition, making it integral to the dynamics of baseball.
