Dedeaux invested $500 to start a trucking firm, Dart (
Dedeaux
Automotive
Repair and
Transit) Enterprises, which he built into a successful regional business. When his college coach,
Sam Barry, entered the
U.S. Navy during World War II, he recommended Dedeaux to take over the team in for the war's duration. Upon Barry's return in 1946, they served as co-coaches with Dedeaux running the team each year until Barry finished the
basketball season. USC won its first national title in
1948, over
Yale, captained by first baseman
George H. W. Bush. The
finals were held at
Hyames Field in
Kalamazoo, Michigan, settled by a 9–2 win in the third and deciding game. Following Barry's death in September 1950, Dedeaux became the sole coach and proceeded to build on his early success to establish the strongest program in collegiate baseball. Prior to his retirement in June , Dedeaux's teams won ten additional
College World Series titles in
Omaha, including five straight (1970–74) and six in seven years. No other coach had won more than three titles until 1997. At USC, Dedeaux coached dozens of future
major leaguers, including
Ron Fairly,
Don Buford,
Tom Seaver,
Dave Kingman,
Roy Smalley,
Fred Lynn,
Steve Kemp,
Mark McGwire, and
Randy Johnson. Throughout his USC career, he accepted a nominal salary of just $1 per year since his trucking business supplied him with a substantial income. He retired as the winningest coach in college baseball history with a record of 1,332–571–11 (), and Dedeaux became known as "The Houdini of Bovard" for the come-from-behind home-field wins by the Trojans. A new baseball field named
Dedeaux Field opened in
1974, named in honor of the active head coach.
Olympics Dedeaux was the head coach of the United States baseball teams at the
1964 Summer Olympics in Tokyo and the
1984 Summer Olympics in Los Angeles, where baseball was contested both times as a
demonstration sport. The 1964 team played one game as part of the Olympic program, defeating a Japanese amateur all-star team, while the 1984 team finished second in a field of eight teams, winning its first four games and losing to Japan in the final game of the tournament.
Films Dedeaux also served as the baseball coach and consultant for actors and ballplayers on the
1989 film
Field of Dreams. While Dedeaux was critical of the "phoniness that was in baseball movies," an opinion which he acquired while working as an extra in the
1948 film
The Babe Ruth Story, he accepted the task after reading the original novel
Shoeless Joe and brought Buford along to help him coach the cast.
Phil Alden Robinson, who directed the film, stated that ballplayers were prepared for the film by Dedeaux. ==Personal==
