Grayson Greiner #21 – USC Retro Throwback Catcher Jersey
 
Leadership. Toughness. Game control.
 
The Grayson Greiner Retro Throwback Jersey celebrates one of the most dependable catchers in South Carolina baseball history. Known for his durability behind the plate, steady leadership, and no-nonsense approach, Greiner was the backbone of the Gamecocks defense.
 
As USC’s field general, Greiner controlled the game from pitch one—handling elite pitching staffs, shutting down running games, and delivering in pressure moments. He played the position the hard way: blocking balls, taking hits, and putting the team first every night.
 
This retro jersey honors a catcher who embodied grit, accountability, and championship standards.
Built for fans who respect the grind and the players who do the dirty work, this jersey represents Gamecock baseball at its toughest.
