The Arizona Diamondbacks signed free agent pitcher Jason Grimsley to a one-year contract the team announced on Wednesday. Per club policy, terms of the deal were not disclosed. The deal is pending on Grimsley passing a physical with team doctors. The 38-year-old right-hander went 1-2 with a 5.73 earned run average in 22 games with the Baltimore Orioles last season. Grimsley made a return to the league in mid-July after having Tommy John surgery on October 12, 2005. The 14-year veteran has a career record of 41-56 with a 4.76 ERA and has also played for Philadelphia, Cleveland, the Angels, New York Yankees and Kansas City.
