You make the call!

Hello Umpires!

I hope you and your families have all been well over the winter. I’m sure we’re all very excited for the summer to kick off and get back on the diamond as soon as possible.

For those of you who I haven’t had the chance to meet just yet, my name is Max Dieks and I’ll be the Umpire-in-Chief as well as the scheduler for the 2021 baseball season.

You can reach me by email at over the course of the season.

With regards to getting the season started:

Level 1 & 2 Umpires

Similar to last year, Thornhill Baseball Club will be hosting the online self-directed modules for you to complete to obtain/maintain your Level 1/2 certification for the 2021 season. I’ll be sending out more information by the end of March on how to register.

Level 3 Umpires

Baseball Ontario will be offering this year's clinic virtually to obtain/maintain your Level 3 status. There will be 8 dates to choose from between March 6th and May 1st and you MUST register by March 31st.

If there are any further questions, please don’t hesitate to reach out by email and I’d be more than happy to help.

Be well! See you all soon.
