This might sound odd, but um...
Furry OCing MLB teams
I don't know, it seems like a challenge compared to doing it with NFL. Only a few teams are based on animals, and the rest have only colors and letters to go off of. I'd also ignore their actual mascots and go off the look and feel of the teams (some of them make no sense anyways

The obvious ones are Blue Jays, Cardinals, Cubs, Diamondbacks, Marlins, Orioles, Rays and Tigers. Simply transpose their team colors to the OC.
Some of the easier teams to imagine (regardless of their official mascots) are:
Astros: Chimpanzee
Athletics: Elephant (based on their old logos)
Braves: Hawk
Brewers: Golden Retriever
Mets: Rat
Nationals: Eagle
Padres: Mule
Pirates: Parrot
Rangers: Horse
Reds: Fox
Rockies: Mountain Goat
Royals: Lion
White Sox: Tuxedo Cat
That leaves 9 I'm having trouble with, either because I can't choose or I got nothing:
Angels: I wanted to cut down on bird OCs, so no dove or anything
Dodgers
Giants
Guardians
Mariners: I wanted a scaley boi to represent my team based on one of the primary colors, but it seems more reasonable to have a dolphin or whale for this
Phillies
Red Sox
Twins
Yankees: I thought horse, but I gave that to the Rangers as that makes more sense
Any ideas?
