The Red Sox released Marlon Byrd, Sean McAdam of CSNNE.com reports (on Twitter). The team had designated the ACES client for assignment earlier this month to clear a roster spot for Daisuke Matsuzaka.
The Red Sox acquired Byrd from the Cubs for Michael Bowden and Hunter Cervenka in April, but the outfielder hit just .273/.288/.333 in 105 plate appearances in Boston. Byrd, 34, is now a free agent and can sign with any team for a pro-rated portion of the MLB minimum.
