R1 on 3B R2 on 1B

[AtlUmpSteve]

Q1. There is never a force when a fly ball is caught. No runner must advance when BR is put out before reaching 1B. So, run scores, no matter how many different appeals are made (unless R1 left 3B early, or missed home), or unless the out is made before R1 crosses (not necessarily touches) home.

Q2. The definition of an appeal is a play that cannot be ruled on until the defense makes the appeal. Unless you do high school softball in South Carolina, that should be self-explanatory.
