⚾ Autographed/Signed Paul Konerko Chicago Black Baseball Jersey JSA COA – A James Spence Authentication Certified Autographed Chicago White Sox Black Alternate Jersey Signed by Paul Konerko, the First Baseman Who Anchored the South Side for Sixteen Seasons and Hit the Grand Slam That Defined the 2005 World Series

⚾ Paul Konerko spent sixteen seasons as the most consistent presence in the Chicago White Sox lineup, becoming the franchise leader in home runs, RBI, and the kind of durability that earns the right to have a number retired. But in the collector's memory, there is one moment that stands above the rest: Game 2 of the 2005 World Series, the seventh inning, and Konerko's grand slam off Houston Astros reliever Chad Qualls that turned a deficit into a lead the White Sox would not surrender. The Sox won the 2005 World Series in a sweep, their first championship since 1917, and Konerko's grand slam was the center of the championship narrative. This autographed black alternate jersey, authenticated by JSA, is a signed piece from the player who gave the South Side that moment. Condition: NOS.

⚾ The black alternate jersey is one of the White Sox's signature looks – part of the distinctive visual identity that separates Chicago's South Side franchise from the Cubs across town and from most of the American League. Konerko wore #14 through his White Sox career, a number the franchise retired in a ceremony that acknowledged both his production and his leadership on teams that ranged from rebuilding to championship-caliber. Six All-Star selections across his tenure documented what the White Sox organization and the American League already knew: when the lineup needed a professional at-bat or a run-scoring situation required execution, Konerko was the presence in the middle of the order. Condition: NOS.
