Sid Fernandez Steiner & MLB Authenticated Autographed MLB Baseball-Retired unorthodox yet effective pitcher Sid Fernandez has personally hand-signed this MLB baseball and inscribed it EL SID. Fernandez had an unorthodox pitching motion with a hesitation at the end followed by a sudden slingshot sidearm delivery. This deceptive motion coupled with an effective curveball and a rising fastball made him a major strikeout threat throughout his career. Fernandez strikeouts were often commemorated by Mets fans in the outfield upper deck with taped signs marked with the letter S for Sid. Fernandez was also part of the 1986 Mets pitching rotation that eventually led to a championship. This Sid Fernandez autograph is guaranteed authentic and includes a Steiner Sports Certificate of Authenticity and an accompanying tamper-evident Steiner Hologram. The Steiner Seal Means Its Real. It also features a Hologram from MLB Authentication.
