📣 DAD’S TAKEON MITCH KELLER
Look at this guy posing like he's about to throw a fastball through a wall, meanwhile his jersey says "PGH" like the Pirates ran out of budget for the full word. That yellow uniform makes him look like a crossing guard who wandered onto the field, and with an ERA over 4 for his career, maybe he should've stuck with directing traffic instead.
ABOUT MITCH KELLER
Mitch Keller has really turned into the ace Pittsburgh needed, putting up some seriously impressive numbers since becoming a full-time starter in 2023. Over his first three seasons as a regular, he's been a workhorse averaging 183 innings per year with elite control, keeping that WHIP right around 1.05. His stuff is legit too, he struck out 11 Cardinals in a complete game gem back in April 2025. Since he doesn't have traditional rookie cards, collectors are chasing his early base cards and any numbered parallels from his breakout years, especially anything from that 2023 season when he really established himself.
Beginning with his first MLB at bat season in 2023, Mitch averaged 183 innings a full 17.5 strikeouts and a 1.05 WHIP over three years. His 2025 highlight was a 9-inning, 11-strikeout performance against St. Louis on April 9.
