I must say I've never seen such a bizarre listing from MLB.com Auctions.

"Bid now to win this helmet worn by Octavio Dotel in the 2011 ALCS Game 3 played against the Texas Rangers on October 11, 2012. . Hologram number FJ 894033."

Where should I start with all the problems?

1) This auction says that the helmet was worn in both the 2011 and 2012 ALCS, the latter date of which has not occurred yet.

2) Unless this auction was written by an oracle divining a future event, Dotel was on St. Louis, not Detroit, for the playoffs.

3) Pitchers don't bat in the ALCS, so the helmet, strictly speaking, cannot be considered game-used.

4) The hologram does not attribute the helmet to any particular player.

Hologram number FJ894033 was located in the MLB Authentication Database under GAME-USED BATTING HELMET.

EVEN WORSE, THE AUCTION HAS HAD 4 BIDS AND IS UP TO $30.

I have contacted MLB.com Auctions, and they have yet to respond or correct the errors.
