Petit to start Giants' Cactus League opener

SCOTTSDALE, Ariz. -- Since the spring schedule has forced the Giants to wait a couple of days before launching their exhibition rotation in earnest, Yusmeiro Petit will start Wednesday's Cactus League opener against the Oakland A's.

Thursday is a scheduled off-day for the Giants. Rather than treat it as an interruption, the Giants will begin using their projected starting pitchers in sequence Friday, when they play split-squad exhibitions against Oakland and Milwaukee.

Petit finished last season impressively as a starter, posting a 4-1 record from Aug. 27 on. But he's apparently competing with left-hander David Huff for a long reliever's role.

Javier Lopez and Sergio Romo are among the relievers expected to follow Petit.

Right-hander Kyle Crick, the Giants' top prospect, topped the list of pitchers named to participate in Tuesday's intrasquad game. Others expected to perform are right-handers Clayton Blackburn, Derek Law, Jose Casilla and Brett Bochy, along with left-hander Ty Blach.

Giants excited to gain wisdom from Bonds

SCOTTSDALE, Ariz. -- Giants manager Bruce Bochy expects Barry Bonds to be treated like any other guest instructor when the all-time home run leader arrives here next month.

"I think he can be another [set of] eyes, ears and brains for players to bounce ideas off," Bochy said Sunday.

Said catcher Buster Posey, "It's exciting to be able to see what kind of advice you can pick up." Asked if he would feel comfortable approaching Bonds, Posey replied, "Probably. It depends on the situation."

Jeff Kent, the former second baseman and 2000 National League Most Valuable Player, has been in camp as the first in a series of guest instructors. Besides Bonds, others expected to follow include Will Clark, Rich Aurilia and Randy Winn.

Pagan skips workouts with tight back

SCOTTSDALE, Ariz. -- Center fielder Angel Pagan experienced back tightness and refrained from participating in Sunday's workout.

Manager Bruce Bochy said that Pagan's back "kind of locked up on him" during a pre-workout meeting. Bochy rated Pagan's playing status as day to day but expressed hope that the switch-hitter could resume drills Monday. Asked if he believed he can practice Monday, Pagan said, "Of course."

Bochy said second baseman Marco Scutaro, also plagued by back problems, is "doing a lot better" and even performed some baseball-related activities on an auxiliary diamond. Scutaro still might need at least another 10 days before he can participate in workouts.

Right-hander Santiago Casilla, who arrived late from the Dominican Republic due to visa problems, pitched live batting practice and looked smooth. Bochy was pleased that Casilla's right knee, which forced him onto the disabled list in the middle of last season, apparently wasn't an issue.

"It's neat to see him running around the way he did," Bochy said.
