1969 Topps #584 Don Mason
About Don Mason
Card #584 comes from Topps' sixth series in 1969, showing Mason with the San Francisco Giants. It marks his best season at the plate: 104 games, 250 at-bats and a .228 average, the highest average of his eight seasons, with 51 games at second base and 21 at third. He is not enshrined in the National Baseball Hall of Fame.
Don Mason, born Donald Stetson Mason in Boston in 1944, was a left-handed-hitting second baseman who reached the majors with the San Francisco Giants in 1966 after signing with the Washington Senators out of Parsons College and then being claimed by the Giants in the Rule 5 draft. He spent parts of eight seasons in the National League, five with the Giants (1966-1970) and three with the San Diego Padres (1971-1973), mostly at second base with occasional appearances at shortstop and third. His busiest seasons came in 1969, when he played 104 games for San Francisco, and 1971, when he was San Diego's most-used second baseman with 90 starts there. Mason finished his career with a .205 batting average, 143 hits, three home runs and 27 runs batted in over 336 games. He was never selected to an All-Star team and is not a Hall of Famer. After his playing career ended, he settled on Cape Cod, Massachusetts.
