B1 hit a soft ground ball down third base line fielded by F5. B1 is hit with the throw. What is the call?
A. Interference, umpire judged the batter-runner interfered with F3 fielding the throw by running outside the 3-foot lane.
B. Runner is safe for running completely inside the 3-foot lane even though F3 could not field the throw.
C. Dead ball and batter-runner is out because last foot that contacted the ground was inside the 3-foot lane.
D. None of the above.

Is the running lane primarily in play for throws from F2 around the plate area?

Both A & B are possibilities. "A" primarily due to "umpire judged"; "B" primarily due to "running completely inside".

Thoughts?
