Grady Sizemore won't be unlockable until the release of the 3rd Inning Program at Noon PT (2pm CT/3pm ET) on June 4, 2021.


Once the 3rd Inning Program goes live, players will need to work their way through the reward track by earning XP from playing MLB The Show 21 to get access to Sizemore in Diamond Dynasty.

New challenges like Conquest, Collections, and more will offer chances to earn large amounts of XP, but we won't have more details on that until the 3rd Inning Program is released in full.
