Jason Hammel's breakout season in 2012 was rewarded Friday when he agreed to a one-year, $6.75 million deal with the Orioles to avoid arbitration. He could make up to $300,000 more in performance incentives.

Closer Jim Johnson also agreed to a one-year deal Friday ($6.5 million), leaving just reliever Darren O’Day as the only arbitration-eligible player remaining on the club.

Hammel, 30, went 8-6 with a 3.43 ERA in 20 starts for the Orioles last season.
