According to Drew Davison of the Fort Worth Star-Telegram, the Rangers will go with an eight-man bullpen during the ALCS against the Tigers, removing catcher Matt Treanor from the roster and adding right-hander Yoshinori Tateyama.
The Rangers kept Treanor around as a third catcher during the ALDS so that Ron Washington had the option of putting Mike Napoli and Yorvit Torrealba in the lineup at the same time against southpaws, but that won’t be necessary during the ALCS since the Tigers will be going with all right-handed starters. Torrealba is expected to serve as the primary backup to Napoli, who went 5-for-14 with one home run and four RBI during the ALDS against the Rays.
Tateyama, 35, posted a 4.50 ERA and 43/11 K/BB ratio over 44 innings during the regular season. The Rangers will technically have a nine-man bullpen to begin the series, as Game 4 starter Matt Harrison will be available in relief on Saturday and Sunday.
