ARLINGTON -- Matt Harrison, who would be the Rangers' Game 1 starter should they advance to the American League Division Series, was in the bullpen for Friday's Wild Card game against the Orioles.
Harrison is one of four left-handers available, along with Robbie Ross, Michael Kirkman and Derek Holland.
"I might use him for an inning, it might be multiple innings or it might be a hitter," manager Ron Washington said.
The Rangers have six right-handers in the bullpen. Mike Adams is not one of them. Adams is still working through his physical issues, and it does not look like he will be available in the ALDS if the Rangers advance. He has not pitched since Sept. 27 and has not thrown off a mound since then.
The Rangers also decided to put side-arming right-hander Yoshinori Tateyama on the active roster over hard-throwing righties Tanner Scheppers and Mark Lowe.
Tateyama is one of six right-handed relievers, along with Koji Uehara, Alexi Ogando, Roy Oswalt, Scott Feldman and closer Joe Nathan. Right-handers hit .225 off Tateyama during the regular season.
"Tateyama gives us a different look," Washington said. "He's tough on right-handers."
