NSA Canada Altered Bat Suspension Policy

The USBA has always trying to provide stringent test procedures and rules to ensure the safety and integrity of the game of Slo-pitch but there are always players, coaches and outside agencies who will do their best to get around these rules. The rules were implemented to keep our participants safe and to make this game the safest it can be. With the word “SAFETY” in mind, the USBA will not tolerate anyone who would, in any manner, put our participants in peril. If any official of the USBA suspects that a bat has been altered, they have the right to inspect that bat, even if it has been inspected by another official or officials. They will also have the authority to suspend any player found to be in possession of an altered bat.

The offending player(s) will have two choices:

1. The player(s) can allow the USBA representative to inspect the bat and the USBA representative can reach a conclusion as to whether the bat may have been altered or,

2. The player(s) can refuse to allow the representative to inspect the bat and take an immediate Three (3) year suspension from any and all NSA Canada play with no right of appeal.

After allowing the USBA representative to inspect the bat and the representative has decided that the bat may be altered then the player(s) will have the following two (2) additional options:

A. The player(s) may allow the director to send the bat to the NSA Canada’s Head Office, then NSA Canada will send the bat to the manufacturer for a final determination on whether the bat is altered or,
B. The player(s) may accept an immediate one (1) year suspension without the right of appeal.

During the time of the examination of the bat by the USBA/NSA Canada and/or the Manufacturer, the suspected offending player(s) may continue to play pending the findings from the Manufacturer or a final decision of the USBA. If the Manufacturer determines that the bat has been altered, the USBA may suspend a first time offender no less than one (1) years and no more than three (3) years. The USBA will also keep the illegal bat and a fine of $500 will be payable to the USBA by the offending team. The length of the suspension is at the sole discretion of the USBA. A suspension decision may be appealed to the USBA in writing or in person. The player(s) may not play in any USBA/NSA Canada sanctioned events while their suspension is under appeal. A second time offender under this altered bat suspension process will receive a lifetime suspension.

The responsibility for knowing whether a bat is altered lies solely with the user and/or the owner of the bat. If an individual uses a bat in the USBA or is the owner of a bat that is brought into a USBA game, any suspensions will be imposed without regard to what the individual knew about the bat being altered. An individual must know that his/her bat is not an altered bat if he/she brings one into a USBA game. If not, the individual can be suspended from any and all USBA/NSA Canada activities. The fact that the individual did not know that the bat was altered is not a factor in imposing any suspensions. The question is only whether the bat is altered or not.

A bat is considered altered when the physical structure of the legal bat has been changed in any way, or when an illegal or non approved bat has been made up in such a way as to appear to be a legal bat. Some examples of altering a bat are, but not limited to, the following: Painting a bat, replacing the handle, shaving the handle or barrel, changing the taper in any way (such as by sandpapering), the use of mechanical or manual device to simulate normal wear, applying a solvent to the surface such as fingernail polish remover, removing or replacing the plug in any way other than factory repairs, removing or replacing the knob, changing the knob in any way, removing or adding anything to the inside or outside of the bat other than the legal way to tape the bat as specified and appropriate in the NSA Canada Rule Book.

** Please note, the use of a flare or cone grip does not constitute an altered bat for purposes of this suspension policy but it still makes a bat altered for game play per Rule 3, Section 1, sub-section k of the NSA Canada Rule Book.

A team, player or coach may protest a bat during play so long as they adhere to the restrictions of Rule 11 in the NSA Canada Rule Book. Bats may be protested only during play and only by participants of the game being played. The fee for the protest of a bat is $400, payable to a USBA representative at the time of the protest. This fee is refundable to the protesting team, player or coach when and if the protest is upheld, less a handling fee of $50 to cover the expenses of testing and shipping the bat.
