[Az.Ump]

Section 1. THE BATTER BECOMES A BATTER-RUNNER.

E. When a fair batted ball strikes the person, attached equipment, or clothing of an umpire or a runner.

6. Touches a runner in contact with a base:
EFFECT: The runner is not out. The ball is live or dead depending on the position of the fielder closest to the base.

Section 8. RUNNER IS NOT OUT.

M. When hit by a batted ball while touching the base, unless the runner intentionally
interferes with the ball or a fielder making a play.

A. Runner interference includes:

c) A runner could be standing on a base and a defensive player
bumps the runner while watching the flight of the ball. If the
defensive player fails to make a catch on a ball that could
have been caught, it is the umpire’s judgment whether or not
interference should be called. The rule provides that a runner
must vacate any space needed by a fielder to make a play on
a batted ball, unless the runner has contact with a legally occupied
base when the hindrance occurs. In this case, the runner
should not be called out unless the hindrance is intentional.

44. RUNNER HIT BY A FAIR BATTED BALL.
A. While in Contact With the Base. A runner who is hit by a fair batted ball
while in contact with the base should not be called out unless the act is
intentional. The ball remains live, or becomes immediately dead, depending
on the closest defensive player. When the closest defensive player
is in front of the base that the runner is in contact with, the ball remains
live. However, when the closest defensive player is behind the base, the
ball is dead. Should the ball be ruled dead and the batter awarded a
base hit, only runners forced to advance because the batter was placed
on first base shall advance one base.
