Don Wilson Lock (July 27, 1936 – October 8, 2017)[1] was an American professional baseball player and outfielder in the Major Leagues from 1962 to 1969 for the Washington Senators (1962–66), Philadelphia Phillies (1967–69), and Boston Red Sox (1969).

He stood 6 ft 2 in (1.88 m) (1.88 m) tall and weighed 202 pounds (92 kg), and threw and batted right-handed.

Instead, he was recalled from the Triple-A Richmond Virginians on July 11, 1962, and traded to Washington for veteran first baseman and pinch hitter Dale Long.

Lock played left field for Washington that season, but by early 1963 he became the Senators' regular center fielder, supplanting the colorful Jimmy Piersall, who was traded to the New York Mets.

Overall, Lock appeared in 921 games over eight seasons, batting .238 with 122 home runs and 373 RBI.
