The Red Sox announced after today's game that they were optioning both catcher Dusty Brown and right-handed pitcher Devern Hansack to Triple-A Pawtucket. The move confirms that, barring a trade, George Kottaras will be the backup catcher charged with receiving Tim Wakefield's knuckleballs at the outset of the season. The moves leave the Red Sox with 38 players in major-league spring training camp.
