Batter prevents ball from rolling fair

[greymule]

The NCAA book deals with this situation, but somebody at headquarters better look up contacting:

9-9-b-2

"The batter may not, after contacting a foul ball, intentionally deflect the course of the ball in any manner while running to first."

In describing interference, the OBR book twice cites "intentionally deflects the course of the [foul] ball." I was wondering why neither NCAA nor OBR used simply touches, but I guess they're trying to cover blowing on the ball or digging a groove in the ground in front of the ball.
