Martin (shoulder) could be activated Sunday if he checks out OK after Friday's rehab outing, Christoper Smith of MassLive.com reports.
Boston manager Alex Cora described it as a "good chance" Martin will be available for the Red Sox this weekend. Martin threw an inning for Triple-A Worcester on Friday, allowing a pair of unearned runs and two hits. Presumably, the Red Sox will want to see how Martin responds Saturday before making a decision on activating him.
