Trembley began managing in the minors in Kinston (I didn't know that, until just now) in 1986. Back then, they were the unaffiliated Kinston Eagles. He moved to the Pirates organization from 1987 to 1989. After a break from managing in 1990, he managed Charleston (in the Padres) organization from 1991 to 1992 and Wichita (also Padres org.) in 1993. Trembley then spent time in the Cubs organization 1994 to 2002, managing Orlando, Daytona, West Tennessee and Iowa. His first stop in the Orioles organization was in 2003, when he was tapped to manage AA Bowie. He spent 2 seasons in Bowie, then 2 at the Orioles then-AAA team in Ottawa, before managing the Orioles in 2007.
I mailed to Trembley on October 12 and got the cards back on October 19, for a 7-day TAT.
