For the pitcher nicknamed "The Big Hurt", see Stan Williams (baseball).
Frank Edward Thomas, Jr. (born May 27, 1968) is a former Major League Baseball designated hitter and first baseman.
Thomas became one of baseball's biggest stars in the 1990s, playing for the Chicago White Sox. Broadcaster Ken Harrelson coined the nickname "The Big Hurt" for Thomas in the 1992 season. Frank Thomas is known for his menacing home run power; he routinely swung a rusted piece of rebar (reportedly found during a renovation project in Old Comiskey Park) in the on-deck circle.
