Stop checking cards one by one

What one sync unlocks
Your binder becomes a plan—not just a list of cards
The importer connects the same owned-card data to every personal tool, so Programs, Collections, squads, and market decisions stay in context.
My Programs
Build one owned squad for several active Programs
Use exact mission progress to remove completed work, stack useful overlap, and carry a position-valid roster into Team Builder.
My Collections
Rank the next reward worth pursuing
Compare closeness, cards owned, remaining route cost, downstream rewards, and squad impact.
Always know what is current
See sync freshness, priorities, and progress together
Sync now imports your club first and completes Program Sync in the background, while optional scans add deeper mission and collected-card detail.
Three ways to import
Start with Sync now. Run the scans when you need them.
Sync now keeps My Club current. The two optional scans check more pages on the MLB The Show website when you want extra Collection or Program detail.
02Optional
Scan program rewards
Checks each visible Program to see which direct player rewards you have earned and which are still ahead of you.
Direct player rewards only; choice-pack selections are not included.
03Optional
Scan collected cards
Checks which cards MLB The Show marks as Collected, meaning cards you have already locked into a Collection, not just cards you own.
Run this when you want the most accurate My Collections status.
Turn dupes into stubs
See which duplicate cards are worth selling
Spot sellable dupes, stacked cards, and price movers you already own.
Build your best squad
Find the best cards in your binder
See your best option at each position by Meta, OVR, Power, Contact, Speed, or Price.

Your MLB password stays with MLB The Show
Your MLB login cookies are never uploaded
Long scans save where they stopped
If MLB pauses a scan, the importer retries
