You make the call!

Greetings Fellow Umpires!!

My name is Paul Chapley and I am the Umpire in Chief and Assignor for the Thornhill Baseball Club.

I am already very excited for and looking forward to the 2023 season. To renew acquaintances with returning umpires as well as meeting all new umpires whether they are youth or adult. There is a space on this page to connect with me if you are considering joining our ranks this summer or you can feel free to contact me –

Be sure to check for emails from me during the off season as I will be passing on details for spring clinics, equipment options and other news related to the upcoming season. I don’t want you to miss any information.

I look forward to being in touch.

    I will ensure that I am knowledgeable of the rules.

    I will control my temper.  Personal criticism of any person by word or gesture is unacceptable.

    I will show respect for the participants and their skills.

    I will refrain from profanity. Verbal abuse towards players, managers, coaches, officials or spectators will not be tolerated including emails, voice messages, text messages (as well as “tweeting”) and social network postings.

    I will not allow use of tobacco, alcohol or drugs (unless prescribed by a licensed physician) on the field or in the dug out or in the vicinity thereof.
