Sitting here at the computer and reading the description, my first thought would be obstruction, providing the ball remained fair.

The original post never provided the final disposition of the batted ball. Obstruction is a delayed dead ball. If the ball was declared foul, we have a strike added to the count and the batter returned to the plate. No obstruction.

I also think this would be a difficult call imagining it in real time on the field. What was the timing between when the fielder stopped playing the ball and the contact with the BR? If it was a fraction of a second and the ball was still fair, I can certainly see an umpire ruling interference.

I am also curious as to the call on the field, what was protested and the outcome.
