Manager Kirk Gibson was happy with what he saw from the right-hander, who has been on the DL since Aug. 3 with right shoulder inflammation.
"He threw good," Gibson said. "I'm not sure what the exit plan is for the disabled list, but it looked like he was throwing the ball good."
Though Gibson was unsure of the exact course of action for Gutierrez, he speculated as to what might happen in the near future.
"Leo threw live [batting practice] [Wednesday]," Gibson said, referring to right-hander Leo Rosales, who has been on the DL since April 29 with a right foot sprain. "My guess is [Gutierrez] will probably do something like that."
