Will Clark Signed Baseball

A Will Clark signed baseball is the quintessential collectible for fans of one of the greatest Giants first basemen in franchise history. "Will the Thrill" delivered a .303 career average, 254 home runs, and an 1989 NLCS MVP performance that stands as one of the greatest postseason series in MLB history — going 13-for-20 with 8 RBIs against the Cubs. Our 5 authenticated signed baseballs feature Clark's clean, athletic signature on official MLB Rawlings balls, each authenticated with a full COA and tamper-evident hologram. Select pieces include inscriptions referencing his nickname or career milestones.
