According to a baseball source, the Red Sox have agreed to a one-year contract with relief pitcher Koji Uehara. The Dallas Morning News was first to report the agreement. (For Uehara's career statistics, click here.) 
The 37-year-old Uehara spent 2012 with the Rangers, finishing with a 1.75 ERA in 37 games. He struck out 43 while walking just three, managing a 32.5 percent ground ball rate.
Uehara broke into the major leagues at 34-years-old with the Orioles, pitching with Baltimore until he was dealt just before the non-waiver trade deadline in 2011. The righty played on a one-year, $4 million deal in '12.
