0 outs, B4 hits deep fly to right catches but everyone is wheeling (and they drop relay ball is rolling around), R3 tags on third and scores, 2 misses third and scores, R1 behind him scores, BR obviously is out. Appeal is on R2 missing third.
Which runs score?
Only R1 (preceeding) not following (R3 who was forced?)
I think following runner scores, and preceding runners do not, but see reference.
