On May 8, 1971, the Oakland A’s trade first baseman Don Mincher, catcher Frank Fernandez, and pitcher Paul Lindblad to the Washington Senators for first baseman Mike Epstein and pitcher Darold Knowles. Epstein and Knowles will help Oakland to its first-ever appearance in post-season play.

Mincher, who started his career in the nation’s capital in 1960, adding the 32 year-old first baseman to a small list of major leaguers to have played for both the original and expansion Senators. The veteran infielder will become the only person to play for each franchise when both teams depart from the District of Columbia, 11 seasons apart, making him both an original Minnesota Twin and an original Texas Ranger.
