NCAA 3-8 Field Umpire
SECTION 8. A field or base umpire may take any position desired and shall aid the umpire-in-chief in administering the rules.
a. The base umpire shall make all decisions on the bases except those reserved to the umpire-in-chief, and shall have concurrent jurisdiction with the umpirein-chief in calling time, balks, foul balls, defacement or discoloration of the ball by the pitcher, use of an illegal pitch, when a fly is caught or in ejecting any player for unsportsmanlike conduct or infractions as prescribed by the rules.
b. If there is only one field umpire, this individual shall make all decisions at first and second base and such decisions at third base as cannot be made more conveniently by the umpire-in-chief.
c. If additional field umpires are used, they are referred to as base umpires; and their normal positions are behind third and second bases. They have concurrent jurisdiction with the first-base umpire.
d. Umpires shall require coaches and all personnel to remain in the dugout or dead-ball territory while the ball is in play. No coach or team personnel shall leave the dugout until the ball is dead.
PENALTY—For the first offense, a warning shall be issued. For the second offense, ejection of an offender.
