Which manual says the correct answer is "B"? (By the way...is this a trick question? I don't see any letter "B" among those answers!
).
This one's been knocked around and debated for years. At one point, one of the pro schools was teaching that this was a foul tip, the other that it was not.
To the best of my recollection, a few years ago MLB issued an interpretation that this is indeed a foul tip. The logic was that once the ball is contacted by the bat, you treat everything from that point forward just exactly the same as any other batted ball.
No reference materials available right now...I'm sure that someone will be able to fill in my sketchy account!
