Oh Bob Wickman, I'll never forget you. The former All Star closer for the Milwaukee Brewers sticks out in my mind not so much because he was a great pitcher, but mainly because he had his own poster day in Milwaukee -- after he had been traded to Cleveland. Similarly, you may remember that Tampa Bay had to scuttle Manny Ramirez bobblehead day last year after he tested positive for banned substances and abruptly retired. They gave out "Super Sam Fuld Super Capes" instead.
For the Athletics, the question after the Gio Gonzalez trade is what becomes of the bobblehead scheduled to be given away of him on June 17 at the O.co Coliseum. The date has already been removed from the Athletics promotional schedule. However, as lead time for bobbleheads is months, fans shouldn't be expecting to see a replacement. The good news is that the two other bobblehead days for the Athletics-- Rollie Fingers (Apr. 21) and Scott Hatteberg (Aug. 18) both feature individuals who can't be traded for prospects.
Assuming the Gonzalez bobbleheads are in production or finished, one can only assume they will be destroyed or buried a la cartridges of the Atari game ET.
