You make the call!

Greetings Fellow Umpires!!

My name is Paul Chapley and I will assume the role of Umpire in Chief and Assignor for Select, Rep and our Men’s House League. I am pleased to introduce Reuben Gasee as my assistant who will be assigning
umpires into the House League schedule.

We are all aware of the effects Covid 19 has had on all sports at the Grass Roots level for players, coaches and officials. Please stay tuned to this page for details regarding Umpire Clinics (live or virtual) and any information on how Covid 19 might affect the 2022 season. My hope is that we all do our part – double vax + boost – and baseball in 2022 returns to a semblance of normal.

I am very excited for the 2022 season and meeting all our Thornhill Baseball Club Umpires. If you have any questions, comments or great ideas please contact me at

    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.
