Level 1 & Level 2 Umpire Clinics:

As of Monday, March 16 th, there will be no in-person Level 1 & 2 clinics for the remainder of this season. We will introduce online training so that certification can be achieved for 2020. More details will be shared by April 3 rd.

    Code for Umpires

    I will officiate by the rules.

    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.

    I will be friendly to all participants.

    I will generally warn players of unacceptable behaviour before taking further action for a second offence, although I reserve the right to cite or eject a player for a first offence.
