Barry Zito no longer knows anybody playing on the other side with Oakland. He's not pitching against pals as he did before, when the pressure mounted in such situations and he fizzled. "That was difficult," Zito said. "You almost don't want to develop friendships because you might be pitching against them next week." Zito has settled in to his new scene and outdid his old Oakland team this time, and was backed by Brandon Belt's three RBIs in the San Francisco Giants' 8-6 victory over the Athletics in the Bay Bridge Series opener Friday night.
