So the Granderson program is listed under 1st Inning Program

But do you actually gets any stars for doing it? I’ve done a few missions and haven’t gotten any?

You get 20 stars once you collect the Granderson, then another additional 10 stars if you hit 6 HR online with him

Why did they chose Granderson of all players? Oh well, was a lot easier hitting with him than Ivan "Tucker Barnhart" Rodriguez.
