📣 DAD’S TAKEON RILEY MARTIN
A sixth-round pick from Division II Quincy who broke school strikeout records gets exactly one card in your collection, and naturally it's a sparkly Sandglitter parallel from Update Series. Because nothing says small-college sleeper prospect quite like covering him in glitter. At least Topps waited for his actual MLB debut before printing the thing, which is more restraint than they usually show.
ABOUT RILEY MARTIN
Riley Martin is a left-handed pitcher from Salem, Illinois, who has worked his way from small-college baseball to the Major Leagues. He was drafted by the Chicago Cubs in the 6th round of the 2021 MLB June Amateur Draft from Quincy University. In his senior season, Martin recorded 152 strikeouts in 78.2 innings, setting the school's single-season strikeout record and earning honors including GLVC Pitcher of the Year, GLVC Scholar-Athlete of the Year, and Third-Team All-American recognition. The Cubs promoted Martin to the major leagues for the first time on April 5, 2026. He made his debut during a loss at the Tampa Bay Rays, getting Nick Fortes to bounce into an inning-ending 4-6-3 double play and throwing 10 pitches, eight for strikes.
This collection features a single 2026 Topps Update Series card in the Sandglitter parallel finish, commemorating Martin's rookie season with the Cubs.
