The Boston Red Sox are lining up a move for veteran former Yomiuri Giants right-hander Masumi Kuwata, major league sources revealed Monday.

The Red Sox, who have already acquired Japanese reliever Hideki Okajima and look set to sign Seibu Lions ace Daisuke Matsuzaka, are expected to offer Kuwata a minor league contract that will include bonuses if he is promoted to the majors.
