It has become a tradition for rookies to wear pink backpacks as a rite of passage to becoming a big leaguer.

Washington Nationals newbies are no different.

With several first-year players in the Nats' relief corps, it created quite the scene prior to Friday's 3-2 loss to the host Miami Marlins, as a group of rookies made their way to the pen wearing the backpacks, which were full of snacks.

At least they're putting the bags to use.
