D-Rob, Joba in the fold

The Yankees avoided having to go to arbitration with with David Robertson and Joba Chamberlain today, signing both righty relievers to one-year contracts. Terms were not announced.

Robertson was 4-0 with one save and a 1.08 ERA in a team-high 70 relief appearances in 2011, and emerged as the club's eighth-inning specialist, setting the stage for Mariano Rivera.

Chamberlain was 2-0 with a 2.83 ERA in 27 appearances, mostly in middle relief, before going on the disabled list on June 8 and subsequently undergoing Tommy John surgery. He is not expected to pitch until after the All-Star break.
