Boston makes Koji Uehara deal official

The Boston Red Sox announced on Tuesday that right-handed Koji Uehara has signed his deal. It's $4.25 million, which is $250,000 more than he made for the Rangers last year.

ESPNBoston.com's story adds this interesting tidbit:

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.
