"Third baseman Scott Rolen tested his back with a session in the batting cage before Sunday's game.
Reds manager Dusty Baker held off on making out his lineup until Rolen's session. But it didn't matter, Rolen couldn't play.
"It's better," Rolen said. "I can walk around like a normal human being. But I've got to see if I can play Major League Baseball."
Obviously, the Reds could use Rolen.
"We're a different team without some of these guys in there," Baker said. "Still, we've been in position to win. We will win. We're going through a very unfortunate period right now. These last two days … those hurt. It hurts when they do it to you, but you expect it when you do it to them."
Baker is looking forward to the off day Monday. It's the first since the day after Opening Day."
