If F3 is playing the throw near the base and contacts the BR, that's not OBS in any code. Collisions that involve legal contact both ways are possible when the ball, fielder, and runner arrive at the same time at a base.

If the throw is nowhere near the base and F3 hinders the BR on his way to fetch the ball, that would likely be OBS.
