David Ortiz plans to accept the offer of salary arbitration that the Red Sox extended to him, according to a source. The decision means he'll return to Boston for the 2012 season. Wednesday at midnight is the deadline for players to accept arbitration. Ortiz, who earned $12.5 million in 2011 and could get around $15 million in arbitration, was seeking a pay raise, according to source. A two-year, $25 million deal would also have kept him in Boston, but prior to offering arbitration, the Red Sox put a two-year, $18 million deal on the table.
