The Yankees today announced that they have agreed with RHP Joba Chamberlain and RHP David Robertson on one-year, non-guaranteed contracts, thus avoiding arbitration.
Chamberlain went 2-0 with a 2.83 ERA (28.2IP, 9ER) in 27 relief appearances with the Yankees in 2011, holding opponents to a .228 (23-for-101) batting average and retiring 22-of-27 first batters faced (81.5%). He was placed on the 15-day disabled list on 6/8 with a strained right flexor muscle before undergoing “Tommy John” surgery in Pensacola, Fla., on 6/16, ending his season. In five Major League seasons, all with the Yankees, Chamberlain is 20-13 with a 3.70 ERA (382.0IP, 157ER) in 193 games (43 starts).
In 2011, Robertson went 4-0 with 1 save and a 1.08 ERA (66.2IP, 8ER) in a team-high 70 relief appearances with the Yankees, leading all AL relievers in ERA. He held hitters to a .170 (40-for-235) batting average and prevented 34-of-44 (77.3%) inherited runners from scoring. Over his four Major League seasons, all with the Yankees, Robertson owns a 14-6 career record with a 3.03 ERA (202.0IP, 68ER) in 204 relief appearances.
