The Boston Red Sox on Tuesday made the signing of right-handed reliever Koji Uehara official, the team announced. He'll make $4.25 million on a one-year contract.
The 37-year-old Uehara was one of the best relievers in baseball last season for the Texas Rangers, sporting a 1.75 ERA, a 0.64 WHIP and 43 strikeouts (compared to just three walks) in 36 innings. His 14.3 strikeout-to-walk ratio was the third best in the majors since 1900 (minimum 35 innings pitched), according to ESPN Stats & Information. Only Dennis Eckersley was better.
The right-handed Uehara made $4 million last season for the Rangers, missing more than a month with a lat injury.
Uehara has pitched in the majors the past four seasons after a successful career in Japan. He pitched with the Baltimore Orioles from 2009-11 before being dealt to the Rangers in midseason.
