Fair/foul call

[Tru_in_Blu]

I found this in the [ASA] Umpire Case Book 2007:

PLAY 1-42
B1 hits a pop fly between 1B and 2B, and the ball falls untouched to the ground about six feet beyond the base line. The ball has backspin and rolls across the foul line about ten feet from home plate, where it is first touched by F3. B1 advances to 2B on the play.
RULING: This is a fair ball because it first touches the ground beyond the bases in fair territory. B1 remains at 2B and is credited with a couble. (1-FAIR BALL-F)

And here is 1 - FAIR BALL:

FAIR BALL: A legally batted ball that:
A. Settles or is touched on or over fair territory between home and first
base or between home and third base.
B. Bounds over or past first or third base, which is in fair territory, regardless
of where the ball hits after going over the base.
C. While on or over fair territory, touches the person, attached equipment
or clothing of a player or an umpire.
D. While over fair territory, an runner offensive player interferes with a
defensive player attempting to field a batted ball.
E. Touches first, second or third base.
F. First falls or is first touched on or over fair territory beyond first, second or third base.
G. While over fair territory, passes out of the playing field beyond the
outfield fence.
H. Hits the foul pole.

So a ball that touches first, second or third base is fair regardless of what happens after that. Conside the ball that hits the pitcher's plate and bounds off foul between either 1B or 3B and home. An unlikely play would be a line drive that hits 2B on the fly and ricohets to foul territory between either 1B or 3B and home.

But the spinning popup "beyond the bases in fair territory" and then spins off into foul ground between either 1B or 3B and home is a bit less intuitive.

This one I would have gotten wrong.
