Koji Uehara headed to Red Sox, will share bullpen and interpreter with Junichi Tazawa

Right-hander reliever Koji Uehara has agreed to a one-year deal with Boston, the second Texas Ranger after thought to join the Sox joining Mike Napoli who also signed was a free agent.

The 37-year old Uehara became a Rangers spare part after Texas signed Joakim Soria.

Look how incredibly consistent Uehara was with his 513 pitches

Facing 130 batters, Uehara only allowed eight extra-base hits (four homers, four doubles) and only walked three. Batters hit .143 off his fastball and .155 off his slider, the two pitches which accounted for 96.2% of the pitches he threw.

Uehara had some impressive splits in 2012 when he went 0-0 with one save.
