Kevin Millwood doesn't have a formal opt-out clause in his minor league contract with Triple-A Pawtucket, according to a major league source.
However, the Red Sox wouldn't stand in the right-hander's way if he had an opportunity elsewhere.
Millwood is 3-0 with a 2.89 ERA for the PawSox in five starts.
