The A's, in just their fifth season since moving to Oakland, won their first of three straight World Series crowns that year. The title was the first ever by a major professional sports franchise in the Bay Area.
The A's honored the 1972 squad during a pregame ceremony that was attended by a long list of players from that title team, including Rollie Fingers, Vida Blue, Joe Rudi, Gene Tenace, Campy Campaneris, Ken Holtzman, Dave Duncan and Dick Green.
Players from the 1972 team rode in convertibles from beyond center field to near the A's dugout. As they were introduced by master of ceremonies Monte Moore, the former radio voice of the A's, they walked on a red carpet to the infield. A's manager Bob Melvin and his players greeted them along the way.
Fans at Saturday's game received a Fingers bobblehead, and the Hall of Fame reliever threw out the first pitch to Tenace, the MVP of the 1972 World Series.
The A's played a video tribute to members of the 1972 team who have died, including manager Dick Williams, team owner Charlie Finley and Hall of Fame pitcher Jim "Catfish" Hunter. Hunter died of Lou Gehrig's disease on Sept. 9, 1999. His wife, Helen, attended the ceremony, and the A's presented her with a $22,000 check for the Jim "Catfish" Hunter ALS Foundation.
