Apointment of Crew Chiefs

On or before January 15 of each year, the Office of the Commissioner shall appoint an umpire to act as the Crew Chief for each of the crews formed for the championship season. While the Office of the Commissioner may consider seniority along with other factors that it may deem appropriate when exercising its appointment discretion, seniority shall not control in the Office of the Commissioner's choice of Crew Chiefs.

The Crew Chief shall coordinate and direct his crew's compliance with the Office of the Commissioner's rules and policies. Other Crew Chief responsibilities include: leading periodic discussions and reviews of situations, plays and rules with his crew; generally directing the work of the other umpires on the crew, with particular emphasis on uniformity in dealing with unique situations; assigning responsibilities for maintaining time limits during the game; ensuring the timely filing of all required crew reports for incidents such as ejections, brawls and protested games; and reporting to the Office of Commissioner any irregularity in field conditions at any ballpark.

Below are the crews for the 2009 championship season as of April 4, 2009 (crews are subject to change). (Bold indicates Crew Chief; [] indicates year appointed as a Crew Chief; uniform numbers appear below to the left of the umpire's name; the number of years of Major League experience an umpire has appears below to the right of his name.)
