Often overlooked, umpires play an integral part in the Little League experience, as it is they who ensure the game is played properly and fairly. Most Little League umpires have no sons or daughters playing Little League baseball or softball. They volunteer because they love the game and want to give players the best experience possible.

To reach the World Series, umpires must demonstrate expertise at each level of tournament play. Umpires must apply to their region headquarters to be considered for a regional tournament and be endorsed by their district administrator. Once at the regional tournament, umpires are evaluated. Little League uses the evaluations to determine World Series assignments, for which umpires must apply.

As volunteers, World Series umpires receive a nominal stipend to help defray travel costs to Bangor. Once here, they are provided free room and board.
