The salary arbitration story
An unsigned player under the team's control who has accrued at least three years but less than six years of MLB active service is automatically eligible for salary arbitration. The major league service time required for arbitration this offseason was 2 years, 122 days, according to calculations by the commissioner's office and the players' association.
Once a player agrees to arbitration, the MLB Players Association and MLB Labor Relations Dept. exchange salary figures on behalf of the player and the team. The arbitration panel must choose either the player's number or the team's submitted salary for the upcoming season. After arbitration has been requested, the player and the team can and usually do continue to negotiate a mutually palatable deal.
Teams can avoid arbitration by failing to offer a contract by the Dec. 2 deadline, which would make the player a free agent.
Settlements often close before the case goes to an arbitration hearing. The Red Sox have been able to avoid salary arbitration hearings for more than a decade, often settling with players in the days and hours leading up to the scheduled hearing.
Of the arbitration eligible players on the 2013 Red Sox roster, pitchers Andrew Miller, Franklin Morales, Junichi Tazawa, Burke Badenhop, and infielder Mike Carp were tendered contracts along with 21 other players on the 40-man roster. Reliever Andrew Bailey, who has struggled and battled injuries since coming to Boston, and oft-injured outfielder Ryan Kalish, were not tendered contracts.
