A game-used Boston Red Sox hat worn by Roger Clemens during the 1990s. The size 7 3/8 hat was made by New Era and shows signs of moderate wear. Clemens' number 21 is written on the underside of the brim and the pitcher has signed the hat in silver, also inscribing "20 K's" though this cap wasn't worn in a game where he recorded 20 strikeouts. One of the greatest pitchers of all time, Clemens won the first of three Cy Young Awards while a member of the Red Sox and would later add four more with the Toronto Blue Jays, New York Yankees, and Houston Astros. Comes with PSA LOA.
