Bob McKeon is a writer and filmmaker based in Venice, California. His collaboration with Bush Leaguers' childhood friend, and Bush Leaguers co-creator Sam Fletcher began with a humor column in their high school newspaper. They wrote Bush Leaguers as an homage to the satirical comedic voice of The Simpsons, baseball, and New York City.

Sam Fletcher is a writer based in Fairfield County, Connecticut. Bush Leaguers is his first comic book. When he's not thinking about defunct baseball teams and Gilded Age phraseology, he likes to play guitar, eat Mexican food and annoy his wife and two children with irrelevant trivia and facts about world geography.

Joe Flood is a comic book author and illustrator whose work includes Bush Leaguers, The Long Road to Liquor City, Cellies, Pirates of the Caribbean, and Orcs: Forged for War. For the Science Comics series, he collaborated on Dinosaurs: Fossils and Feathers with MK Reed and wrote and illustrated Sharks: Nature’s Perfect Hunter and Birds of Prey: Terrifying Talons. He lives with his wife and daughter in New York’s Hudson Valley.
