On October 14, 1964, after a season during which Williams hit a career-low .159, the Red Sox handed him his unconditional release. At 35, Williams was at a career crossroads: Richards gave him a spring training invitation but no guarantee that he would make the 1965 Astros' playing roster; the Red Sox offered Williams a job as playing coach with their Triple-A farm team, the Seattle Rainiers of the Pacific Coast League. Looking to begin a post-playing career in baseball, Williams accepted the Seattle assignment. Within days, a shuffle in 1965 affiliations forced Boston to move its top minor league team to the Toronto Maple Leafs of the International League. This caused the Red Sox' Triple-A manager, Seattle native Edo Vanni, to resign in order to remain in the Pacific Northwest. With a sudden opening for the Toronto job, Williams was promoted to manager of the 1965 Leafs. As a novice pilot, Williams adopted a hard-nosed, disciplinarian style and won two consecutive Governors' Cup championships with teams laden with young Red Sox prospects. He then signed a one-year contract to manage the 1967 Red Sox.
