Diamondbacks Closer J.J. Putz Overjoyed After Receiving Justin Bieber Autograph (Photo)

The only people that usually get excited about receiving a Justin Bieber autograph are 16-year-old girls. But apparently things have changed, as Arizona Diamondbacks closer J.J. Putz showed when he got a copy of Bieber's autograph.

Putz was apparently overjoyed at finding a Bieber autograph in a pack of Panini cards, flipping the script on the usualy story of an athlete making someone else's day by giving them a signature.

Check out Putz captured in a moment of pure joy from a photo tweeted by teammate Brad Ziegler.
