Choo was in the lineup on Sunday for the third straight day after being sidelined since Aug. 15 with a broken left forearm. Choo appears to be healthy, but the Rangers have to decide if he is up to Major League speed.
"We are still in the process of evaluating Shin-Soo Choo," manager Jeff Banister said.
Choo's situation impacts multiple players. If Choo is ready to return to the regular starting lineup, then he would push either Nomar Mazara or Carlos Gomez to the bench, or put them in a platoon situation in left field.
