A Tiger!?! in Orangefrica!?! The tigers don't have an orange jersey, although one is grey/orange. EDIT: Turns out they sell a "Batting Practice" jersey that is orange. Probably just trying to cash in on the Auburn fans market.
Miami Marlins introduced an orange jersey in 2012, this is what started the trend. They had hints of orange before, but they came out with a bright new orange jersey that soon captured the world's attention because of one guy who went to
all kinds of games wearing that jersey.
Baltimore was the next to bring back the orange although also in 2012 they announced the new jerseys later. Baltimore hadn't had an orange jersey since 1992. Like Miami, this was a major rebrand, and their bird logo took it's current shape.
The Giants have been rockin' orange since 1977 (and originally it was a weird retro orange):
However, their new orange jersey came out in 2014, after 32 years without.
The Astros are very famous for their old orange jerseys, so it made sense after the trend to introduce a new orange jersey in 2013.
So, all the orange gang is back except the Mets.
Why all the orange? Haven't you heard it's the new black?
