Interference after being safe

[rafking]

Two situations below in which some might say I could have called interference, but I did not. I hope I can explain them clearly. Fed rules. I maybe stuck on 8-6-13. "...runner causes illegal contact and alters the actions of the fielder in the immediate act of making a play on her."

1. R1 on 1st; R2 on 2nd. BR hits a grounder up the middle to center field. Center fielder throws to F6 for a possible force on R1 at second. R1 does not slide. Ball arrives late for an easy safe call. R1 collides into F6 as her momentum carries her. F6 ends up on the ground with ball rolling out of glove. R2 is on third now, but does not attempt to come home to my surprise. The play ends. My thoughts: R1 clearly interferred with F6, but F6 had no play anywhere, so I did not call it based on "she did not interfere with a fielder making a play". The play at second was over and all other runners were standing on a base and not moving. I guess if R2 would have tried for home, then I would have called something.

2. Very same situation on a play at home. Bases loaded and a grounder to the infield. Runner on third coming home, beats the throw easily, no slide. Catcher is set up on first base side of the plate. Momentum carries her into catcher and knocks her to the ground. No runners advance further and they remain on their base. Case 8.6.18 helps me with this. It says that run does score as interference occurred after the run, so can not call her out. Then I can only call another runner out if the interference prevented the catcher from making another play. There was no play to make.

Thoughts?
