I was recently attempting to clean up some areas where I store my collection when the below card popped up in a stack of 2010 Topps USA Baseball cards.
Bregman had a fine introduction to the bigs and I think he's going to be a really, really good player. He's already become one of my six keepers for my fantasy league in 2017 and I'm happy to have stumbled upon this hidden gem. While it's not an official RC I essentially consider it as one. Because if Topps can call 18 different cards a rookie, I can think of this one as such.
