ASA Rules Question From Prospective Ump

[greymule]

When the runner retreats toward the base last occupied, the force is reinstated and the runner does not have to be tagged. You will find this under the definition of "force out." In ASA, this is interpreted to include a runner who touches 1B and retreats toward home plate.*

*You should know that OBR does not include the BR retreating toward home plate after touching 1B. In OBR, the runner is not considered "forced" and did not "occupy" home plate; therefore, he must be tagged.
