Corrales has long been associated with Dodgers president Stan Kasten, having served as Bobby Cox's bench coach in Atlanta when Kasten was president there and taking the same role in Washington when Kasten was president there.
Corrales, a former Major League catcher, also was the first Major League manager of Mexican-American descent and the fourth manager to skipper two teams in the same season (Philadelphia and Cleveland in 1983).
"We are very happy to have Pat join us," Colletti said in a release. "His vast experience, especially from his years in Atlanta and Washington, will be a great strength to our organization. He will assist us in a variety of ways, including evaluating our player-development system and helping us at the Major League level. I have known Pat for a long time, and some of my early mentors, whom I respect very much, have worked side by side with him."
