MLB-Designated Theme Days.
Players are prohibited from wearing items and using equipment consistent with a Major League Baseball-designated theme for a specific game day (e.g., Mother’s Day, Father’s Day, Memorial Day, Independence Day, etc.) except for such specific items or equipment that have been approved and communicated with reasonable advance notice to the Players Association and the Clubs’equipment managers.
Violations of this policy will be deemed to be flagrant under Paragraph 4 of Section O, below.
To the extent that a Player desires to wear an item or use equip ment that is not authorized for use on an MLB-Designated theme day, the Player must obtain advance approval from the Commis sioner’s Office, which approval shall not be unreasonably with held, provided that: (a) the color and design of the item or equipment is consistent with that of the particular theme day; (b) no corporate logos or distinguishing marks are displayed on the item or equipment; and (c) the category of item or equipment has been approved for use in Major League games on non-theme days. It is encouraged that the manufacturer of the item or equipment contributes funds to the designated charity of the theme day.
In addition, the Office of the Commissioner shall: make available to Players, if practical, non-logoed items or equipment if the Player wants to participate in the theme day event but does not desire to use a product manufactured by the designated corporate sponsor; and, provide the Players Association with recognition supporting theme day. A player who declines to participate, in whole or in part, in any MLB-designated theme day shall be per mitted to wear any item or use any equipment he would otherwise use/wear during a non-theme day.
