Piazza 's game-winning 8th-inning home run in the first professional baseball game played in New York following the 9/11 attacks has been called iconic , therapeutic , and symbolic . The jersey he wore in that September 21 , 2001 game was purchased in April 2016 for $ 365,000 , the highest price ever paid for a modern-day jersey , and is displayed on a rotating basis among the 9/11 Memorial Museum , Citi Field , and the National Baseball Hall of Fame
