What does it take?

  • Willingness to learn and gain experience
  • Love of the game
  • Confidence and pride
  • Hustle, physical and mental alertness
  • A sense of fair play and impartiality

How much does it pay?

Remuneration is based on the level of baseball officiated & the card level of the umpire.
The higher card level, the higher level of pay.
The higher the level of ball, the higher the level of pay.

What does it cost?

Each umpire must go through an annual umpire clinic. Clinics take place in the spring and vary in length depending on the clinic level.

When at all possible, you will be paired with more experienced umpires to help you with any on-field concerns that might arise.
Kingston Thunder ensures you are paid on a regular basis throughout the season.
