obstruction from another board

[mcrowder]

The crux of the problem here:

"Runner DOESN'T alter path" vs. "I'm not sure if runner has slowed down a little or not."

As umpire, this is your decision. Did the runner alter his/her path ("alter" includes slowing) at all? If so, OBS. If not - did contact with the player without the ball slow the runner (thus "altering" the path of the runner while not in possession of the ball)? In this case, no - contact with the runner happened AFTER possession of the ball. No OBS.
