BOSTON — Dave Dombrowski didn't have to go far in his search for a new Red Sox general manager — his man was already in the office.
Dombrowski stayed in-house by hiring Mike Hazen as GM Thursday, promoting him to help rebuild a team that went from World Series champion to the AL East cellar — with a second straight last-place finish well on its way.
Hazen, 39, has been with Boston since 2006, and his promotion from assistant GM is the first big move by Dombrowski since he took over as president of baseball operations in August.
"He's been interviewing every day since I've been here, per se," Dombrowski said. "I've been very impressed with Mike since I've been here."
Dombrowski said he had a list of "about 30 names," but decided to hire from within.
"For me, what it came down to is the experience that he's had at the major league level, and he's part of the organization," he said. "You promote from within when you have good people."
Hazen replaces Ben Cherington, who built the 2013 World Series champions but had the Red Sox headed for last place for the second year in a row. Cherington decided not to stay on when Dombrowski was brought in above him in August.
Hazen said Cherington backed his decision to go after the position.
"Nobody five weeks ago was proud of where we were," Hazen said. "We aren't today. It's hard to see one of your good friends that poured his soul into this job, what happened. When we sign up for this line of work, we realize what the ramifications can be when the product on the field isn't what it needs to be.''
Hazen, a Massachusetts native, is the sixth Red Sox GM in a row with New England roots. He grew up a Red Sox fan, arguing with his dad "who was better between (Jim) Rice and (Dwight) Evans.''
A two-time All-Ivy League outfielder at Princeton, Hazen was selected by the Padres in the 31st round of the 1998 draft. He played two seasons in the minor leagues before joining the Cleveland front office.
After five years with the Indians, he was hired by the Red Sox as director of player development in 2006.

Royals: RHP Greg Holland, who leads the team with 29 saves but has been erratic, has a right elbow ligament tear that will end his season and likely require surgery. The severity of the injury will be determined next week. The tear was detected Aug. 31, but Holland tried to pitch through it.
