GLENDALE, Ariz. -- The A's want your Giants caps.
No, really. They're willing to give fans a new green and gold cap in exchange for their East Bay loyalty.
As part of a release announcing plans for Spirit Week leading up to Opening Day, the A's are urging fans to trade in a Giants cap for a new A's camp at all public events during that span, including the April 1 Bay Bridge exhibition game at the Coliseum.
The celebration of a new season -- the A's 50th in Oakland -- begins Monday, when Oakland mayor Libby Schaaf will join A's fans in raising the team flag above Oakland City Hall.
