America is losing its fascination with bobbleheads

according to this article, which also confirms what you already expected, that the Pirates' 12 bobblehead promotions are more than twice the number held by other teams.

It's been seriously suggested that the Pirates will wait until after Friday night's Sean Casey bobblehead promotion to trade him, and based on the criteria that this team uses to make decisions, I have no doubt that this is true. If Casey is traded between Friday and Monday night, I'm guessing that it will be the quickest change in status from bobblehead honoree to former team member in the history of Major League Baseball.
