This New York Yankees Camoflauge 7 5/8 fitted baseball hat is autographed by the greatest relief pitcher in MLB history, Mariano Rivera. Rivera signed this hat on the inside of the bill and inscribed "Sandman" under his signature. In 2019, Rivera became the first player ever to be inducted unanimously into the National Baseball Hall of Fame. He holds the all-time saves record with 652. He was awarded the MVP of the World Series in 1999 and the ALCS in 2003 after stellar series performances against the Atlanta Braves and Boston Red Sox, respectively.
