In the play under discussion, as described, the runner made contact with the fielder a half second after he fielded the ball and in so doing prevented the fielder from making a good throw to retire the batter-runner. I believe the correct call is runner OUT, BR to 1b.

You're correct. Mea Culpa. I forgot that wording. I've decided to punish myself by re-reading MLBUM on my way to my football game today.
