What happens if a runner misses a base while running the bases?

When a runner misses a base while running the bases, that missed base can lead to serious consequences regarding the legality of their run. If a runner does not touch a base while running the bases, they can be called out if the defense appeals the missed base.

In the case where a runner misses a base and later crosses home plate, the run will not count because every base must be legally touched in order for the run to be valid. Even if the player touches home plate, if it is determined that they failed to touch a previous base and that the defense makes an appeal to that effect, the run does not count. This reinforces the importance of running the exact path and ensuring all bases are touched in the correct order. Touching all bases is fundamental for a legal run to be scored in baseball, so any failure to do so directly impacts the scoring of the game.
