The Red Sox are showing interest in left-hander Erik Bedard, according to a source. Privately, Boston is worried about the back issues of Clay Buchholz. Bedard is scheduled to pitch Friday night in Seattle against the Rays, his first start since June 27. The day after that start he was placed on the DL with a sprained left knee. If the Red Sox believe Bedard is healthy, they'll make an offer for him this weekend.
