Peter Magowan, the former San Francisco Giants executive who thwarted a relocation attempt and championed construction of the waterfront stadium now called Oracle Park, passed away Sunday at age 76 after a long fight with cancer. "The Giants family, the entire Bay Area and the game of baseball lost a man whose passion and loyalty to his favorite team and beloved community made it possible for all of us and future generations to experience the magic of Giants baseball in San Francisco forever," Giants president and CEO Larry Baer said in a statement.
