 When the Dodgers acquired the Los Angeles franchise of the Pacific Coast League in January 1957 — the precursor of the Brooklyn club's historic shift to the West Coast, which would follow at the close of the 1957 baseball season — Walsh, as an Angeleno, became president of the minor league team and a liaison between the Dodgers and the city of Los Angeles.Then, after the Brooklyn club moved West in 1958, Walsh became assistant general manager of the Dodgers.He focused on the team's efforts to build a ballpark in Chavez Ravine, and when Dodger Stadium opened as a state-of-the-art facility in 1962, Walsh was named director of stadium operations.
