2017 Topps Stadium Club Baseball

Chrome parallels joined the Stadium Club formula in 2017, adding a 90-card chrome run on top of the 300-card base set and 50 base image variations. Hobby boxes again held two autographs, and every pack carried an insert or parallel. Base Card Autographs is the deepest signed set at 68 cards, with Beam Team, Power Zone, Scoreless Streak and Co-Signers all offering autograph versions of their inserts. The Mystery Redemption Autograph pair was later revealed as Cody Bellinger and Ian Happ.
