When the ball is dead and runners have ceased running the bases, a high school team on defense can make a verbal appeal that a runner failed to touch a base or to tag up. Once the appeal is communicated to an umpire, he can make a ruling.
[OBR: they must put the ball back in play]
If a high school team wants to appeal a runner’s failure to tag up or touch a base, but another play has happened, the appeal is still allowed if the offense initiated the play. This might happen when the offensive team knows the defense wants to appeal, so they send a runner on an attempt to steal a base so he can draw a throw. The appeal is still allowed unless the pitcher balks (which is considered an illegal pitch).
[OBR: when a play ends, the appeal must be made before any other pitch, play or play attempt. An appeal throw that goes out of play is considered a play attempt.]
If a high school team on defense wants to appeal a runner’s failure to touch a base or tag up, and they have requested an intentional base on balls, they can no longer appeal.
[OBR: no intentional base on balls.]
If a high school team on defense wants to appeal a base runner’s failure to touch a base or tag up, and the game has apparently ended, they must make their appeal before the umpires leave the field.
[OBR: they have until all infielders have left fair territory.]
