Green Day frontman Billie Joe Armstrong and rapper Too $hort are attempting to keep baseball alive in the Bay Area. The music icons are joining the ownership group of the Oakland Ballers, a new independent team attempting to keep baseball alive in the city.

Last summer, the Oakland Ballers — a Pioneer League baseball team that played its inaugural season in 2024 — welcomed more than 2,200 fans into its ownership group through a community investment round that raised $1.

Armstrong, 53, founded Green Day in 1987 with Mike Dirnt. The band has sold more than 85 million records worldwide and has won four Grammy Awards. Armstrong also won a Grammy for Best Musical Show Album for “American Idiot,” which also featured Green Day.
