The Boston Red Sox fired manager Bobby Valentine on Thursday after one season in which he failed to bring order to a clubhouse that disintegrated during the 2011 pennant race.

Valentine finished with a record of 69-93 on a team that was beset by injuries before management gave up on this season and traded some of its best players — and biggest salaries. Without Adrian Gonzalez, Carl Crawford and Josh Beckett, the Red Sox will save $250 million in future salaries and have a chance to rebuild over the winter.

But that will be too late for Valentine.

A baseball savant who won the NL pennant with the New York Mets and won it all in Japan, Valentine was brought in after two-time World Series champion Terry Francona lost control of the clubhouse in 2011 during an unprecedented September collapse. But the players who had been coddled under Francona bristled under Valentine’s abrasive style and, more importantly, didn’t win for him, either.

“Our 2012 season was disappointing for many reasons,” general manager Ben Cherington said. “No single issue is the reason, and no single individual is to blame. We’ve been making personnel changes since August, and we will continue to do so as we build a contending club. With an historic number of injuries, Bobby was dealt a difficult hand.”

The Red Sox used 56 players in 2012, the most in club history.

“This year’s won-loss record reflects a season of agony,” Red Sox president Larry Lucchino said. “It begs for changes, some of which have already transpired. More will come. We are determined to fix that which is broken and return the Red Sox to the level of success we have experienced over the past decade.”

A year after a 7-20 September cost the Red Sox a chance at the postseason, the club went 7-22 in September and October to put a punctuation mark on its worst season in almost 50 years. But unlike 2011, when the team took a nine-game lead into the final month, Boston was never competitive under Valentine.

“I understand this decision,” Valentine said. “This year in Boston has been an incredible experience for me, but I am as disappointed in the results as are ownership and the great fans of Red Sox Nation. It was a privilege to be part of the 100 year anniversary of Fenway Park and an honor to be in uniform with such great players and coaches. My best to the organization.

“I’m sure next year will be a turnaround year.”
