8:58 PM CST: The Red Sox just sent a press release officially announcing the arbitration offers.
7:22 PM CST: Amalie Benjamin of the Boston Globe confirms (via Twitter) that the offers to Bay and Wagner have been made.
6:09 PM CST: Red Sox president Larry Lucchino told The Providence Journal's Dan Barbarisi that the club will be offering arbitration to Type A free agents Billy Wagner and Jason Bay. Lucchino said the offers would be officially sent out by tonight's 11:59 PM deadline, if they hadn't been sent already.
Neither move is a surprise, given that Boston stands to recoup as many as four extra draft picks should both players sign with other teams.
