We've collected the official baseballs used at the historic St. Louis Cardinals Alternate Training Site right here at Hammons Field, and now you can purchase your own as a keepsake. Each baseball comes with an Authenticated Sticker and Certificate, verifying its use during the St. Louis Cardinals Alternate Site workouts, which included players like Paul DeJong, Dylan Carlson, Nolan Gorman, Matthew Liberatore, Alex Reyes, Carlos Martinez, Jordan Walker and many more. The Alternate Training Site Baseball Theme Package is just $17 and comes with one Field Box ticket voucher to a 2021 Springfield Cardinals home game.
