A HISTORIC WORLD SERIES

The 1989 World Series marked the first all-Bay Area championship matchup between the Oakland Athletics and the San Francisco Giants, earning the nickname “The Battle of the Bay.”

The series is remembered for both its historic rivalry and the dramatic Loma Prieta earthquake, which struck just before Game 3 and temporarily delayed the series.

When play resumed, the Oakland Athletics dominated the matchup, sweeping the Giants in four games. The championship team featured stars such as:

* Rickey Henderson

* Mark McGwire

* Jose Canseco

* Dave Stewart

* Dennis Eckersley

This hat commemorates that historic moment with a detailed World Series patch and classic A’s styling.
