A day after seeing a concussion specialist in Pittsburgh, Orioles second baseman Brian Roberts spoke briefly with reporters. I've been covering Roberts since 2005, and he may have been as morose as I've ever seen him. Asked how he is feeling, he said, "It comes and goes." He said that he'll start doing some physical therapy, including riding the bike. "It's a part of life. You take the good with the bad, so you just try to stay positive and take it day by day," he said. Showalter is planning on having a sitdown with Roberts before tonight's game.
