The right-handed hitter was a solid run producer for the Cardinals until 2014, when lingering foot woes seemed to contribute to the worst season of his career. Craig was acquired by the Red Sox along with Joe Kelly in exchange for John Lackey last July 31, but his struggles only worsened when he came to Boston.
Craig felt he was healthy coming into this season, but he could not get on track as a reserve player with Boston. Over 24 games, Craig hit .135 in 52 at-bats.
In his first five games for Pawtucket, Craig hit .261 with three doubles in 25 at-bats.
