I thought the "pushing" thing had been covered already? Oh wait, that was shoving. Okay, there is no shoving or pushing or any hint of something intentional on the part of either the runner or the fielder in the original post.

Again, intent changes the play and the ruling. If fielder intentionally pushes runner off base then rule obstruction and place runner back on bag, if runner intentionally interferes, call interference and runner out. We're not arguing any of that. The question is sans intent on the part of either player is this an out?
