"That first year I worked with him we just got along," Leary said.
Redmond said he was attracted to Leary's passion for the game.
"He's a great catching guy," Redmond said. "When I was coming up, I loved his approach. We always hit it off. As a player and coach, I trusted him. He prepared me in many ways. It's great having him as a coach. He's great with our catchers. He developed a catching program and guys have responded to that."
Leary said he developed the program after taking things he learned at every level, from high school through the pros.
Leary, who attended College of San Mateo before graduating from LSU, played against current Oakland Athletics manager Bob Melvin, who attended Cal.
A's pitching coach Curt Young knew Leary from their days together with the Boston Red Sox and recommended him for Melvin's staff.
