The Yankees avoided arbitration with reliever Joba Chamberlain, announcing a one-year agreement worth a reported $1.875 million. Chamberlain, 27, missed most of the 2012 season due to a trampoline accident that caused an open dislocation of his right ankle. Chamberlain returned from the grisly injury to pitch 20 2/3 innings with a 4.35 ERA. With Rafael Soriano departed for Washington, Chamberlain figures to team with Mariano Rivera and David Robertson in the back end of the Yankees bullpen. He earned $1.675 million last season. Earlier this week, the Yankees reached a one-year, $7.15 million deal with starter Phil Hughes to avoid arbitration. There are still cases pending for Robertson and fellow reliever Boone Logan. Friday is the deadline for both sides to exchange salary figures.
