Green Day’s Billie Joe Armstrong has purchased a stake in Oakland’s minor league baseball team:
The Green Day icon is joining the ownership group of the Oakland Ballers, the new (and as of this coming season) only professional baseball team in Northern California’s East Bay. Armstrong and legendary Oakland rapper Too $hort are climbing aboard the independent Pioneer League team ahead of the 2025 campaign, giving a celebrity boost to a club that in its first season already attracted plenty of grassroots interest.
