The Red Sox offered Mariano Rivera a two-year, $30 million deal to replace Jonathan Papelbon as their closer, according to a baseball source. Boston was prepared to non-tender Papelbon if Rivera accepted the deal. Rivera turned down the Red Sox to return to the Yankees, who offered the same money as Boston. The Red Sox on Thursday night tendered a contract to Papelbon, who was paid $9.35 million last season and is arbitration-eligible.
