2020 Umpire Information

Umpire Guidelines


MGSA umpires are expected to look and act professional at all times. Be proud of the uniform. Hustle on the diamond and be aware of the proper mechanics.

Be punctual. Arrive at the park at least 20 minutes before game time. You should meet your partner away from the diamond (ex. the parking lot). Go to the diamond together and hold the plate meeting at least 5 minutes before the scheduled game start time.

It is important to always be prepared for the game. Whether you are plate or base umpire, be sure to have your indicator, brush and face mask with you when you arrive at the game. It is also suggested that you wear a Jock or Jockette.

Plate equipment will always be located in the equipment bins at each diamond. It is the responsibility of the Milton coaches to give you access to the bin.

Each bin should include an umpire kit with:

  • Leg protectors
  • Chest protector
  • Mask

Punctuality and No-Shows

Once you have confirmed that you can umpire assigned games, it is your responsibility to meet that obligation. If for any reason you are not able to make your assignment, it is your responsibility to secure a replacement umpire.  Bear in mind that on most evenings every umpire will be scheduled to work or play on their own team so the earlier you try to reschedule the better chance of success.

If a team needs to cancel a game due to bad weather, poor field conditions r if the City has closed the diamond; they must notify the head umpire by 3:00pm on the day of the game. Should I receive late notification (after 3:00pm), the umpires will still be paid for the canceled game.  If the cancellation is because of non-weather related issues, then the head umpire must be notified by the Association with at least 24 hours notice or the umpires will be paid.

Do not miss an assignment. If an umpire is a "no-show", that umpire will have their next pay total reduced by that game's rate.

Umpire Mechanics and Rules

It is important to review both the league and age group rules for the games you will be umpiring.  Each Division within the Milton Girls Softball Association has its own rules that they follow.  Study the rules frequently and plan your plate meeting to include any special rules pertinent to the game.
