Ramirez wasn't in Monday's starting lineup in the series opener against the Indians, but Mattingly said he could possibly be available off the bench. Infielder Miguel Rojas started in Ramirez's place at shortstop Monday.
"I think it's encouraging today that we may have him in some capacity," Mattingly said. "If it's not today, then tomorrow or the next day. At this point, I don't think we're looking at the DL. But we'll obviously see where that goes."
