Mark Kenny, aka (ak47_studios) on Instagram, is a graphic designer who redesigned all of the MLB team's logos with Star Wars themes. The Washington Nationals have been recast as the Washington Rancors, named after the "immense, warm-blooded predator native to Dathomir, Lehon, and Felucia" as wikipedia explains, that Jabba the Hutt tries to feed Luke Skywalker to in Return of the Jedi.
You can check out the rest of Mark Kenny's Star Wars-themed MLB logo-reimagingings through his Instagram page HERE at least until either MLB or George Lucas gets wind of his creations. Who knows, maybe they'll like/promote them to since he's really created some fantastic work here.
My favorites? The Toronto R2-D2s?
The Braves are not really cool enough for the logo he gave them. The Atlanta Bobba Fett Braves:
I think the Pittsburgh C3POS might be my favorite:
The Solo Rangers might be the winners though:
