Bay Bridge Series

The Athletics–Giants rivalry, formerly termed the Bay Bridge Series, or the Battle of the Bay, was a series of baseball games played between—and the rivalry of—Major League Baseball's Oakland Athletics of the American League and San Francisco Giants of the National League. The formerly termed Bay Bridge Series took its name from the San Francisco–Oakland Bay Bridge which links the cities of Oakland and San Francisco. Beginning in 2018, the winner of the annual series retained a trophy fashioned from a piece of the original bridge.
