Giants great Will Clark has personally hand-signed this MLB baseball and inscribed it Thrill. In his first full season as a member of the San Francisco Giants in 1987 Clark had a .308 batting average and was voted in as the starting first baseman for the National League All-Star team every season from 1988 through 1992. He is also the first Giants player since Bobby Murcer from 1975-1976 to drive in 90 or more r in consecutive seasons. 1989 was his finest season in which he batted .333 with 111 RBIs. This Will Clark autograph is guaranteed authentic accompanied by a tamper-evident Steiner Hologram. The Steiner Seal Means its Real.
