The only pitcher with 100 saves and 100 complete games, Dennis Eckersley took an unconventional road to Cooperstown. In the collection is a twice-signed contract with the Autoball company, producers of souvenir baseballs with stamped facsimile signatures. The terms of the deal? The pitcher received one cent per ball sold. Eck signed this contract on March 18, 1975 nearly a full month before his big league debut on April 12 that same year.

With only three career saves to his credit before joining Tony LaRussa’s Oakland Athletics, Dennis Eckersley’s career was not on a Hall of Fame trajectory. Moving to the bullpen changed that. Shown here is his first card depicted as on Athletics player. Eck has signed in boldly in black sharpie. During his nine years in Oakland Eck recorded 320 saves and picked up the 1992 Cy Young and MVP Awards along the way, solidifying his Cooperstown credentials.

His day in the sun came when he was inducted in 2004.
