Baseball Card GM

It all started in 2024, when Garrett Weaver (then just seven) asked a simple question: “How can I actually play with my baseball cards?”

When no games existed, he and his younger brother Simon invented a set of rules at their dining-room table, which today after play-testing with their friends, schoolmates, and baseball teammates has become Baseball Card GM.

The game is a sturdy 36"x18" neoprene playmat (which can be rolled for easy storage/travel) with all rules on the playmat itself. A 9-inning game takes about 30 minutes to play, good for ages 7+.

It's easy as 1-2-3:

1. Draft your team from your own baseball cards.

You are the GM, so you can create any team you want, any way you want, with whatever cards you have!

You can make your ultimate Dream Team, recreate an actual historic team, build along a specific theme (ex: MVP’s and CY’s of the 2000’s), do an actual draft alternating picks with your competitor, or crack some new packs and play with whatever you get. The possibilities are endless, and even a random stack of cards can be hours of fun.

The game works best with baseball cards from the 1980’s to today (ie most likely to have all the stats needed for the game: HR, 3B, 2B, Avg, BBs, Hits, RBIs, SBs), but you can use older cards as well because the stats used in the game are nearly universal to all cards.

Once you have your team, you will build your line-up, choose your starting pitcher, and fill out your bench and bullpen. Then you are ready to play ball!

2. Use the stats on the back of the cards.
