Red Sox manager Bobby Valentine said Friday that he is bracing for the likelihood that David Ortiz (Achilles) will miss the rest of the season. Ortiz is making progress after receiving a platelet-rich plasma injection on August 27, but he hasn't been cleared to begin running. With the Red Sox out of the race, there's little reason for him to rush back and risk further injury going into free agency. "I'm not sure that that's the official word yet," said Valentint. "Just prepare just in case he's not going to come back. It's not really my call. I mean, if he's healthy and he loves to play the game of baseball, he could always go out there and bat it around a little. I'd hate to jeopardize his career, that's for sure."
