Brian Roberts (concussion) is now taking ground balls and also hitting in the batting cage. "It's definitely part of the progression," he said. "Every day that goes by and you don't feel worse, you're encouraged for sure." The next step for Roberts is to take live batting practice, though it's not clear when that will happen. "At some point coming up, hopefully," Roberts said. "I talk to my doctor every night and we kind of lay out a plan for the next day." It's so far, so good for Roberts, but he's obviously still got a long ways to go.
