A Major League source told the Globe tonight that the Red Sox are working on a plan to add Class AAA Pawtucket lefthander Andrew Miller to the rotation.
Miller has a clause in his minor-league contract that would allow him to declare free agency tomorrow if he is not promoted to the majors.
Miller has been one of the best pitchers in the International League in recent weeks. In his last five starts, Miller has allowed seven earned runs over 30.1 innings with seven walks and 30 strikeouts.
Miller went 5.1 innings against Charlotte tonight, allowing one run on five hits with one walk and 10 strikeouts. He has a 2.47 earned run average this season.
According to the source, the Sox are planning to start Miller against the San Diego Padres next week and will create space in the rotation by shifting around the starts of John Lackey and Tim Wakefield. That would create essentially a six-man rotation.
The Red Sox have not commented on what their plans are for Miller. Speaking to reporters earlier today, manager Terry Francona praised Miller’s performance and said he personally recruited him over the winter.
There is no word on when Miller would be added to the roster. But presumably the promise of being added to the rotation would keep him from exercising his out clause tomorrow.
Several teams in need of a starter, including the Yankees, have scouted Miller in recent weeks. Were he to opt-out, it’s almost certain that he would be added to a major league roster.
