📣 DAD’S TAKEON RILEY O'BRIEN
Riley O'Brien is one of those middle reliever guys who suddenly gets saves and the manufacturers act like he's the next great closer. Panini rushed him into 2026 Update with a rookie variation because he had six saves in two months. That's the problem with modern cards. Every guy who closes five games gets the rookie treatment years after his actual debut. His real rookie year was 2021 with the Reds but nobody chased those cards. Now they're hyping 2026 stuff for a guy who might be back in setup duty by next month.
ABOUT RILEY O'BRIEN
Riley O'Brien was born February 6, 1995 in Seattle, Washington. After two seasons at Everett Community College, he transferred to the College of Idaho. He was selected by the Tampa Bay Rays in the eighth round of the 2017 Major League Baseball draft and made his MLB debut in 2021 with the Reds. O'Brien has played for three teams: the Cincinnati Reds, Seattle Mariners and St. Louis Cardinals. On November 5, 2023, O'Brien was traded to the Cardinals, and on March 26, 2024, the Cardinals officially announced that O'Brien had made the Opening Day roster.
