Koji Uehara’s inability to keep the ball in the ballpark since coming to the Rangers in a midseason trade with the Orioles has gotten the previously dominant reliever removed from the World Series roster.
Texas also removed fellow reliever Yoshinori Tateyama from the roster, adding right-hander Mark Lowe and catcher Matt Treanor in their place.
Treanor will serve as the Rangers’ third catcher behind Mike Napoli and Yorvit Torrealba, while Lowe will replace Uehara and Tateyama in a low-leverage middle relief role after missing the past month with a hamstring injury. Lowe had a 3.80 ERA and 42/19 K/BB ratio in 45 innings during the regular season.
Uehara’s struggles obviously led to his removal from the roster, but it also speaks to Texas’ exceptional bullpen depth that Uehara and Tateyama aren’t needed after combining to throw 109 innings with a 3.22 ERA and 128/20 K/BB ratio this season. For a lot of teams they’d be the primary late-inning relief options.
