Welcome Umpires!

Umpires play an important role in Tigard Diamond Sports. They contribute to the development of our players, promote equity and fairness, and contribute to the positive culture within the organization. Umpiring is a terrific way for individuals to develop self confidence, leadership identity, and courage. For more information about being a Tigard Diamond Sports umpire please see below.

Umpire Rain Out Procedure

On days with questionable weather, here is what umpires must do:

  • Managers will notify the Umpire In Chief or Assistant Umpire in Chief by no later than one hour before the scheduled start time for each game to notify them if a game has been rained out.
  • If your game is rained out, you will receive a text or an email informing you. If you do not receive a text or an email, your game is on.


Coaches Rain Out Procedure

Coaches, your rain-out procedures are on the Game Day Information page.  

Emergency Hotline

If you have an emergency that requires you to cancel:

  • Call John Smith, Umpire in Chief: (503) 702-5749, or
  • Call __________, Assistant Umpire in Chief: ________________
  • If you are not able to actually speak with John or _______ please send a text message to both their cell phones.

Last minute cancellations cause a great deal of hardship for the umpire staff, your umpire partners and league managers.  Last minute cancellations (within 48 hours of game time) will be tracked and may cause individuals to be subject to sign up restrictions. 

Umpire Uniforms

While umpire uniforms are not required, the goal is to look official, different from the teams on the field, and non-attention grabbing. 

Preferred attire is as follows:

  • Black, Navy Blue or Light Blue polo shirt with as little advertising as possible
  • gray or dark pants (long pants are preferred over shorts)
  • dark hat with no logo
  • jackets or cold weather gear should be dark colored, when possible
  • water bottles encouraged

Please remember, it is always colder on the fields than you think it will be.  Also, the sun is usually setting by the end of the game, so temperatures cool off.

If you are looking for options for this gear, Goodwill, Value Village or any other second-hand store are valid options!

Umpire Policies

Communication of assignments will occur through the Umpire Schedule online spreadsheets. Umpires will not be e-mailed their assignments.  Since each umpire signs up for their own games, it is  expected that umpires are aware of their game assignments and are tracking their own game schedules.

Multiple last minute cancellations (within 48 hours of game time) or missed assignments may result in the limitation of sign up opportunities for those offending umpires.

Tigard Diamond Sports Umpire Game Sign Up Process

Umpire Scheduling and Confirmation Process - umpire responsibilities are highlighted in red:

  The Umpire-in-Chief (UIC) or Asst. UIC, or "Umpire Staff" will email all registered umpires with links to the upcoming game schedule documents.  Umpires will be notified in the email of what dates are open for sign ups. (Anyone signing up for games beyond the open period will have their names removed in an effort to keep things fair for everyone.)
  • Umpires should review all Umpire Schedules (JV, Majors, AAA, AA) and fill in their names for any open games/positions that they desire to work.
  • The Umpire Staff will send out an e-mail that will ask for additional help  from anyone that can fill in the upcoming open positions
  • Umpires wanting the open spots should e-mail the Umpire Staff who sent the email  with their requests and availability
  • The Umpire Staff will directly email the umpire(s) that are assigned to each open game
  • Umpire(s) who receive an email from the Umpire Staff should reply to confirm for that game

Umpire Payment Process

For umpire payments, the goal is to issue checks 3 times during the Spring season and 2 times during Fall Ball.   Checks will be mailed to the address provided on the umpire registration page.  If you have any questions once you receive your check, please e-mail us.  You should always keep a record of games/dates that you have worked! 

Please remember that all folks involved in preparing umpire checks are volunteers and are doing this work on their own time.  Every attempt is made to issue checks in a timely manner.


For questions contact the Umpire in Chief John Smith.
