Jimmy Piersall became a professional baseball player at age 18, signing a contract with the Boston Red Sox in 1948. In a reserve role with the New York Mets, Piersall played briefly under manager Casey Stengel. In the fifth inning of the June 23 game against the Philadelphia Phillies, Piersall hit the 100th home run of his career, off Phillies pitcher Dallas Green. He ran around the bases in the correct order, but facing backwards as he made the circuit. Jimmy Piersall has hand signed this Cleveland Indians MLB Licensed 8x10 Photo.
