Chicago — The Red Sox on Tuesday night announced Dave Dombrowski, fired by the Tigers this month after 14 years, will be their next president of baseball operations.

General manager Ben Cherington will not be staying in Boston, out of a job less than two years after winning a World Series.

"A great opportunity with a quality organization," Dombrowski told The News. "I'm very thankful for the opportunity. I look forward to doing this."

And president Larry Lucchino stepped down Aug. 1, the same day Tigers owner Mike Ilitch called Al Avila and made him the team's general manager.

Dombrowski was informed he was out of a job Aug. 4 after overseeing perhaps the greatest period of sustained success in Tigers history, including five playoff appearances and two World Series bids during a nine-year span.

But Dombrowski, 59, never delivered a World Series title, and when Ilitch was told in late July his team — with a payroll in excess of $170 million — would have to give up on its title hopes this season, Dombrowski's fate was sealed.

In Boston, he'll be reunited with owner John Henry, who owned the Marlins when Dombrowski was their general manager.

"I am very happy for Dave," Avila said from Chicago, where the Tigers and Cubs were in a lengthy rain delay. "I knew he would be hired quickly and Boston is the perfect place, rejoining with John Henry."

The Red Sox spend lavishly, and annually have great expectations. They, however, have been in a two-year tailspin after winning the World Series in 2013.

Dombrowski will be charged with finding some pitching, as just about every move Cherington made in the offseason — including acquiring Rick Porcello from Detroit, then extending him for $82.5 million — was a bust.

He'll also have a decision to make on manager John Farrell, who is on leave after being diagnosed with cancer.

The Red Sox, who employ math man Bill James, are an interesting landing spot for Dombrowski, who's not the biggest believer in advance metrics.

The Blue Jays, Angels and Mariners also were believed to have some level of interest in Dombrowski, who will maintain his home in Metro Detroit and commute from Boston while his children finish school.
