Identifying the most popular player in the history of the Chicago White Sox points toward legendary Hall of Fame slugger Frank Thomas, affectionately nicknamed "The Big Hurt," who dominated American League pitching during the 1990s and early 2000s. As a two-time American League MVP and the offensive centerpiece of the franchise, Thomas led the White Sox with incredible power and discipline, eventually anchoring the organization's legacy. Other beloved historical figures like Luis Aparicio, Minnie Minoso, and modern World Series champions like Paul Konerko and Mark Buehrle also hold exceptionally revered status among the South Side faithful for their championship heroics and enduring dedication to the club.
