Runner stealing 3rd base. Hot ground ball hit up the 3rd base line, runner slides, F6 playing behind the bag, ball hits runner:
#1 before contact with the base while sliding.................Interference!
#2 after contact with the bag, while in contact with the bag, runner still lying on the ground...................Interference?

#1 is actually what happened. I called the runner out....Interference........... I was PU, saw him stealing out of the corner of my eye, so when ball hit, I was looking right down the 3rd base line.........
