The Red Sox have "maintained dialogue" with free-agent right-hander Roy Oswalt, according to a report. Boston saw the rival Yankees fortify their starting rotation via trade and signing on Friday night. New York acquired Michael Pineda from Seattle and signed Hiroki Kuroda. "The Yankees did well by waiting out Kuroda," one National League executive said, referring to the one-year, $10 million deal Kuroda signed. "The Red Sox could do the same with Oswalt."
