Giancarlo Stanton ... the 2016 Home Run Derby champion.
Luis Severino ... not having a good year with the Yankees with an ERA approaching 7.00
And finally ... Buster Posey, one of the cornerstones of the Giants.
I really like the design of these. It's a simple design that wouldn't seem out of place as insert set in either the flagship sets or in Stadium Club. I probably won't be chasing these at all but if I happen to buy any more pizza or breadsticks that have these in them, I won't complain.
As for the breadsticks that accompanied these cards, they were better than I thought, especially after you dress them up with a little extra cheese.
