Tip 1: Just Play, Have Fun, and Grind out a Nest Egg
In order to get to the point where you can have an additional source of Stubs beyond just playing the game, you need to well, um, play the game. Just about everything you do in MLB The Show 16 will reward you with Stubs.
Since you’re most likely trying to earn Stubs so you can enhance your Diamond Dynasty team or RTTS player, go ahead and just play that for a little while. Actually, just go and have fun with the game you purchased. In addition to getting the Stubs you’re looking for, you’ll make progress in the game type you’re trying to use Stubs to enrich.
For example, if you’re trying to build up a good Diamond Dynasty team, whenever you complete a head to head game, you’ll receive some cards which could be upgrades to your team that you didn’t have to spend a single Stub for, or, at the very least, something you could feed to your created character.
Whatever mode you choose, just play it for a little while until you have a couple thousand Stubs to play around with.
