Carlos Marmol said he will throw three to four innings on a brief rehab stint with Triple-A Iowa next week before returning from the disabled list.

Marmol is due off the DL on May 27 and said he should be able to return to the Cubs. When or if he returns to the closer role is unknown.

"I'll be ready soon," he said. "I have to figure out how to pitch good again, and I don't know what will happen after that."
