Bobby Valentine lasted one season in Boston.
The Red Sox announced via Twitter that the beleaguered skipper won't return in 2013, one day after the team concluded a 93-loss season
"Our 2012 season was disappointing for many reasons," Red Sox general manager Ben Cherington said in a statement. "No single issue is the reason, and no single individual is to blame."
Valentine, 62, becomes the first scapegoat for a season that seemed doomed from the start. He was hired in December amid an organizational turnover that saw manager Terry Francona and general manager Theo Epstein not return.
Valentine quickly alienated the clubhouse, beginning in April when he said fan favorite Kevin Youkilis wasn't "as physically or emotionally into the game as he has been in the past for some reason."
Later in the season, players went to ownership to lodge formal complaints.
On Wednesday, Valentine told reporters that he "had every opportunity to succeed and didn't."
He also told Boston sports radio station WEEI that he felt he was undermined at times by some of his coaches.
Valentine leaves with one season lft on his contract. The last-place Red Sox finished with more than 90 losses for the first time since 1966.
