Michael Lynn Squires (born March 5, 1952) is a former Major League Baseball player who played for the Chicago White Sox primarily as a first baseman from 1975 and 1977 to 1985. He won the American League Gold Glove Award at first base in 1981. Squires was best known as a defensive player, often coming on in late inning situations when the White Sox had a slim lead. He did not have the typical power associated with a corner infielder, never hitting more than two home runs in a season. Nonetheless, he was a valuable member of the White Sox of the early Tony La Russa era, particularly in their 1983 AL West championship run.
