He also was the co-author of two books on the mental approach to baseball: The Mental Game of Baseball: A Guide to Peak Performance (1989) and A Champion's State of Mind (2005).
Montreal Expos' manager (1976)
In 1976, Kuehl was named the second manager in the history of the Montreal Expos franchise, although he did not complete a full season in the job. His Expos won only 43 of 128 games (.336) and were in last place in the National League East Division when Kuehl was replaced by Charlie Fox on September 4.
He began his managing career at the young age of 21[2] as the player manager of the unaffiliated Salem Senators of the Class B Northwest League in 1959.
After weathering the 1976 debacle, Kuehl remained in the Major Leagues as a coach with the Minnesota Twins[3] under manager Gene Mauch, whom he had replaced in Montreal. He also served under Mauch's successors, Johnny Goryl and Billy Gardner, during his six years (1977–1982) with the Twins.
Kuehl then headed the player development department of the Oakland Athletics from 1983 through 1995, a period when the A's had one of the most productive farm systems in baseball. After leaving Oakland, he spent two seasons (1996–1997) in the front office of the Toronto Blue Jays. From 2001 to 2007, Kuehl was special advisor, baseball operations, for the Cleveland Indians.
