On most baseball teams, the manager and the bench coach work closely together and are often close friends. But Bobby Valentine and Tim Bogar went long stretches without speaking this past season.
Valentine was fired as Red Sox manager Oct. 4, and on Thursday came word from team sources that Bogar will not be returning.
Bogar, 45, spent four seasons with the Sox. He was the first base coach in 2009, the third base coach from 2010-11, and then the bench coach.
New Red Sox manager John Farrell is expected to name Torey Lovullo as his bench coach. Lovullo was considered by Valentine for the job last December before he settled on Bogar.
