Putnam progressing toward rehab assignment

DETROIT -- Zach Putnam, who was placed on the disabled list with right shoulder inflammation last Thursday, will probably need a Minor League injury rehab assignment before he returns to the White Sox.

"Probably a short one," said White Sox manager Robin Ventura.

Putnam has a 2.35 ERA and three saves over 33 games for the White Sox.

"It's going fine," said Ventura of Putnam's rehab work. "Most of it when they're with [White Sox head athletic trainer] Herm [Schneider] I let him do it.

"There haven't been any setbacks, I know that. I haven't seen him play catch yet. I don't pay attention to them when they're on the DL."
