Oakland's four remaining arbitration-eligible players -- first baseman Yonder Alonso, outfielder Josh Reddick, relief pitcher Fernando Rodriguez and third baseman Danny Valencia -- filed for arbitration Tuesday, which was the first day those players could begin the process.
Reddick, who made $4.1 million last year, is in his final year of arbitration prior to becoming a free agent, and Valencia, Alonso and Rodriguez are each in their second year.
Friday is the deadline for the A's and the players to exchange desired salary figures for 2016. The midpoint between what the player wants to be paid and what the team wants to pay him generally serves as a launch point for contract negotiations.
