Tigers general manager Dave Dombrowski revealed Monday that Andy Dirks played through a lingering knee injury all season that he suffered in spring training. "We think he would have had a more contribution from an offensive perspective (if he had been healthy)," Dombrowski said. "He finally acknowledged it bothered him. It has been nothing major. A doctor looked at him. He's done rehab." Dirks batted just .256/.323/.363 with nine homers during his disappointing 2013 season. He'll enter spring training healthy but hasn't been guaranteed anything from a playing time perspective.
