Rolen, out since May 12 with a strained left shoulder, took batting practice and fielded ground balls on Wednesday for the first time since he went on the disabled list. He did it again on Thursday.
"I felt good and I'm ready to go out and do it again and progress this way," Rolen said before heading to the field on Thursday. "No timeline."
Rolen planned on dialing back the number of ground balls he took on Thursday. The club will continue to watch him carefully, and is not rushing a return. But they're pleased with the results so far.
"He looked pretty good," Reds manager Dusty Baker said of Rolen's Wednesday BP on Thursday. "Today is a key day and tomorrow and the next day and the next day. It's how he looks in successive days."
