5:13pm: GM Dave Dombrowski told Beck that he would be "very surprised" if Rodney or Lyon accepts arbitration.
1:16pm: The Tigers offered arbitration to Type B free agent relievers Fernando Rodney and Brandon Lyon, but not Type A second baseman Placido Polanco, writes MLB.com's Jason Beck. These decisions fit with our predictions from yesterday.
The Tigers most likely want to go in a cheaper direction at second base, and Polanco benefits because his new team will not have to surrender a draft pick. I am guessing they do not expect Rodney or Lyon to accept the arbitration offers, but wouldn't mind if either one does.
