Joba Chamberlain and the Yankees have agreed on a one-year, non-guaranteed contract for 2013, avoiding salary arbitration. Two Yankees remain in arbitration: right-hander Robertson and left-hander Boone Logan. New York's projected payroll is at about $200 million for 16 players, including $8.5 million the Yankees are paying Pittsburgh as part of last year's trade that sent A.J. Burnett to the Pirates. After suffering through some shaky outings in August, Chamberlain pitched well through most of September, allowing just four earned runs in 14 appearances.
