CHICAGO -- White Sox reliever Zach Putnam tested the inflammation in his right shoulder that sent him to the disabled list on July 24 by playing catch Friday and then throwing a 20-pitch bullpen session featuring all fastballs.
"I felt really good," Putnam said. "I'm not trying to force it right now. Just trying to feel it out."
Manager Robin Ventura had suggested Putnam might need a short Minor League injury rehab assignment before returning to the White Sox. But Putnam sounded as if that assignment might not be needed.
"With the way I feel physically, if I had to get in there tomorrow, I think I'd be OK," Putnam said. "It's just a matter now of fine-tuning, having not thrown for a week, trying to shake the rust off a little bit."
Putnam plans to add some cutters to Sunday's bullpen session, with his split-finger being the last pitch incorporated.
