After the Orioles' workout had ended Saturday and many of his teammates had headed to the clubhouse, Brian Roberts put on his batting gloves and headed to a back field to take a few more swings. It was an encouraging sight to the Orioles after the second baseman had missed their previous three workouts with a stiff neck, renewing concerns about his health. "I wasn't worried about it being anything major, but any time you're hurt as a baseball player, you got to think about it. I wasn't overly concerned," Roberts said. "I felt fine. I was just trying to get some extra swings to get back into it." Roberts, who had X-rays taken on his neck Wednesday and was dealing with muscle spasms, had downplayed the discomfort all along, saying it was unrelated to the herniated disk in his back that limited him to 59 games last year.
