Rolen took batting practice, fielded ground balls and ran without issue. He said it felt good swinging again.
"As good as I can feel," Rolen noted.
"That's real good," manager Dusty Baker said. "It gives me another weapon off the bench. It makes us feel better to see that he feels better."
Rolen could return to the lineup on Saturday.
"It's possible. We'll see how he looks today," Baker said.
