What occurs if a base coach physically assists a runner while a fly ball is in play?

When a base coach physically assists a runner while a fly ball is in play, the appropriate ruling is that the runner is immediately called out. This situation stems from the specific rules governing baseball and softball that prohibit any form of physical assistance to a runner who is trying to advance while the ball is in play. Interfering with the play in this way undermines the integrity of the game and alters the outcome of the play, which is why an immediate out is enforced in this scenario.

The consequences for such actions are intended to maintain fair play and uphold the rules of the game. This prohibition helps ensure that all runners advance on their own merit without external help, thus promoting integrity in the competition. The enforcement of this rule serves as a critical teaching point about the nature of specific plays and situations in baseball and softball.
