I got this info from BigLeagueBaseballs.com, the Cardinals and Royals are using special commemorative items to raise money for tornado victims in Joplin, MO. According to the different articles I read it is difficult to tell if the commemorative baseballs are going to be only ceremonial first pitch or also used in the game. I have read conflicting information. If anybody sees a game used ball with the logo I will gladly offer a reward/finders fee/trade on an authenticated one.
