The Boston Red Sox announced the signing of reliever Koji Uehara on Tuesday.
Uehara, 37, will receive a one-year deal with a $4.25 million base salary, according to Jon Paul Morosi of FOX Sports.
The righty posted a 1.75 ERA in 36 innings in 2012, but missed time with a strained lat muscle. He'll join Andrew Bailey and Junichi Tazawa in Boston's bullpen. The Red Sox have spent $124.45 million to sign Uehara, Mike Napoli, Shane Victorino, David Ortiz, Jonny Gomes and David Ross.
