  • Uniforms (jersey, pants, socks & cap) will be handed out at the start of the season once team rosters have been set

  • NOTE - While umpires are rounding into competent baseball officials at this level, it is still expected that the coaches support our umpires and their calls.  Players are to leave the playing field if they are called out on the bases or strike out, and are to avoid any angry confrontations with the umpires.  Any difficulties with umpires can be brought to the attention of a Convener or the Umpire Coordinator
