Pull rod and jump ball are two different concepts, and there is no such thing as pull rod jump ball. The pull rod refers to the rod method of hitting the middle and lower position of the cue ball to make the cue ball retract after hitting the target ball. The jump ball in the nine balls requires hitting the part above the middle of the cue ball. If the ball is "picked up" under the cue ball, it is a technical foul and the opponent gets a free ball.
