"The people in this room know what we have and the people in the front office know what we have, so it's not a question of us having to believe something that isn't there," right-hander Tyler Walker said. "People can think what they want. Nothing starts until Opening Day, March 31. That's when the rubber meets the road."Pitching matchup
SF: LHP Barry Zito (11-13, 4.53 ERA in 2007)
Zito has registered at least 10 victories in each of his seven full seasons, including five with at least 14 wins. He's one of 10 left-handers in the Giants' San Francisco history to start on Opening Day. LA: RHP Brad Penny (16-4, 3.03 ERA)
Penny's .800 winning percentage last year was the best in the Major Leagues. He became the first Dodgers starter to make consecutive All-Star teams since Ramon Martinez (1990-91).
Dodgers closer Takashi Saito has thrived against the Giants, posting an 0.86 ERA (two earned runs in 21 innings) in 20 appearances against them. ... Russell Martin hit .368 against the Giants last year. ... Jeff Kent has an injured hamstring, but might drag himself from the training table to face his former teammates, given his success against them last year (.366, three home runs, 12 RBIs).
