William Frederick Gardner (born July 19, 1927) is an American former professional baseball player, coach and manager. During his ten-season active career in the Major Leagues, Gardner was a scrappy, light-hitting second baseman for the New York Giants, Baltimore Orioles, Washington Senators/Minnesota Twins, New York Yankees and Boston Red Sox. His only significant time on any team was with Baltimore, where he spent four straight full seasons from 1956–59. He threw and batted right-handed, stood 6 feet (1.8 m) tall and weighed 170 pounds (77 kg). After retiring as a player, he spent over 20 years as a coach or manager, and managed the Minnesota Twins and Kansas City Royals during the 1980s.
