Mincher's early years in the majors were marked by his role as a platoon player, often sharing first base duties. Despite this, he quickly demonstrated his ability to hit for power, a trait that would define much of his career. In 1961, he was part of the Senators' roster during their final season before the franchise relocated to Minnesota and became the Twins. With the Twins, Mincher found more opportunities to showcase his skills, particularly during the 1963 season when he hit 17 home runs.
The 1965 season was a highlight for Mincher and the Twins, as they won the American League pennant. Mincher played a crucial role in their success, hitting 22 home runs and driving in 65 runs. The Twins faced the Los Angeles Dodgers in the World Series, and although they ultimately lost, Mincher made a memorable contribution by hitting a home run in Game 1 against the legendary Sandy Koufax.
In 1967, Mincher was traded to the California Angels, where he continued to be a reliable power hitter. His tenure with the Angels was marked by his first All-Star selection in 1967, a testament to his growing reputation in the league. After two seasons with the Angels, Mincher was selected by the Seattle Pilots in the 1968 expansion draft. As a member of the Pilots, he became an integral part of the team's inaugural season in 1969, leading the team with 25 home runs and earning his second All-Star selection.
The Pilots' franchise moved to Milwaukee and became the Brewers in 1970, and Mincher continued to play a significant role on the team. However, his time with the Brewers was short-lived, as he was traded to the Oakland Athletics midway through the 1970 season. With the Athletics, Mincher added veteran experience to a young and talented roster. In 1971, he played a part in the Athletics' journey to the postseason, although they were defeated by the Baltimore Orioles in the American League Championship Series.
Mincher's final MLB season came in 1972, when he was traded back to the team where his major league career began, the Washington Senators, who had by then become the Texas Rangers. He retired at the end of the season, concluding a career that spanned 13 years and included 200 home runs and 643 RBIs.
After retiring as a player, Mincher remained involved in baseball, eventually becoming the president of the Southern League, a Double-A minor league, where he served from 2000 to 2011. His post-playing career was marked by his dedication to the development of the game at the minor league level.
