Chase signatures from international phenom Roki Sasaki, 2024 NL Rookie of the Year and 2025 Cy Young candidate Paul Skenes, and 2025 AL MVP candidate Bobby Witt Jr. The checklist also features top draft picks such as Travis Bazzana, Chase Burns, Charlie Condon, Nick Kurtz, and a wide range of projected future first-rounders, including Jamie Arnold, Xavier Neyens, Eli Willits, Brady Harris, and more. Key prospects like Jesus Made, Kyle Teel, Bryce Eldridge, and Cam Smith add even more depth.

Every autograph in this product is on a card, with dual and triple signed cards plus eye-catching inscription content sprinkled throughout. Numbered Mega Series parallel autograph sets include multiple color bordered designs at low print runs, creating plenty of chase pieces for player and prospect collectors.
