To unlock Donaldson, you'll need to complete a collection that includes 20 out of 24 Negro Leagues cards. This collection spans several different modes and events, and while it's all achievable through gameplay, using MLB 25 Stubs can significantly shorten the grind, especially when hunting down the harder-to-get cards.

Step 2: Jackie Robinson Day Showdown

Each time you complete the showdown, you'll earn a Negro Leagues Choice Pack, giving you access to some valuable players you might be missing.
Step 3: Jackie Robinson Day Program
