At this point, the Sox are bracing for the likelihood that David Ortiz won't play again this season, according to Bobby Valentine. Ortiz missed 35 games with a strained right Achilles, then suffered a setback Aug. 24 and has missed the last 12 games. He received a platelet-rich plasma injection Aug. 27 that, Valentine said, has taken effect. Still, though, Ortiz isn't ready to resume running. And with the Red Sox having fallen out of the wild-card race, there isn't much point to rushing Ortiz back to the field, a point GM Ben Cherington has made during conversations with Valentine. "I'm not sure that that's the official word yet," Valentine said. "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."
