A baseball legend, Jack Dunn is retired from coaching after his 20th season as head coach at Portland State University and his 39th year of coaching baseball. He never had a losing season at PSU, compiling 630 wins. His lengthy career also included 19 years at Portland high schools Cleveland (14 yrs.) and Wilson (5yrs.).

In the Division 1 Pac-10 North Conference, PSU won the title in 1984, advanced to the championship game of the league's post-season tournament in 1986 and 1990. The Vikings also won the NorPac in 1977 and traveled to Tempe, AZ. for the NCAA Regional's. In 1984 and 1986, Dunn's teams won 39 games, the state's collegiate record.

Since 1975, 35 Portland State players have signed professional baseball contracts. Most notable of Dunn's graduates to play major league baseball were pitchers Jeff Lahti, Eric Gunderson and the late Steve Olin. Two-time National League MVP Dale Murphy and Chicago Cubs manager Tom Trebelhorn also played for Dunn when he coached Portland high schools Wilson and Cleveland.

Prior to succeeding Roy Love at PSU in 1975, Jack's Wilson High School team won three straight league titles. His American Legion team, Watco Electric, was so successful that he earned the Slats Gill Award as Oregon's Coach of the Year for all sports in 1973 when Watco finished third at the American Legion World Series. In 18 years under Dunn, Watco won 14 division titles and three state championships.
