In a mild surprise, manager Bruce Bochy said Friday that his tentative regular-season rotation has Tim Lincecum third and Ryan Vogelsong fifth, unexpected because of their respective 2012 seasons.

Bochy would not divulge why he has Lincecum ahead of Vogelsong. Instead, he reiterated his feeling that the order in a rotation this good is not a major issue.

"I don't want these guys to get caught in it, and I don't want to send that message either," Bochy said. "At the end of the year, if they're all healthy, knock on wood, they'll all have the same number of starts."

Matt Cain, Madison Bumgarner and Barry Zito figured to be first, second and fourth. If Lincecum is slotted third, his debut in what he hopes to be a season of redemption will be April 3 at Los Angeles, the final game of the opening series against the Giants' ancient rivals.

"It's always exciting when you face the Dodgers, being in a division like this, where the baseball is played so well and the rivalry is so big," Lincecum said. "Obviously, the Dodgers have made moves this offseason to better their chances, and that will make the rivalry more exciting, so I'm definitely excited to get a chance to get out there again and throw against that team - the L.A. Dodger blue."

Lincecum makes his spring debut Monday - against the Dodgers.
