The famous ballpark gum for athletes of all ages. Founded by former left-handed pitcher Rob ?Nellie? Nelson, Big League Chew started from humble beginnings in the Portland Mavericks bullpen in 1977. Sitting in a bullpen one summer night long ago, Rob Nelson came up with a fun new bubble gum idea: shredded gum in a pouch. He called it Big League Chew. Together Rob and Jim Burton created Big League Chew, and in no time at all, it became the ?must-have? bubble gum for players of all ages. For more than 35 years, the iconic pouches packed with shredded, flavorful bubble gum have become the preferred chewing gum for all ages having sold more than 800 million pouches to date. Made in the USA. Big League Chew Strawberry Tray.
