It has been an unusual start to the season for Giants right-hander Ryan Vogelsong.
While Vogelsong pitched at least six innings in each of his first 21 starts in 2012, he's managed to do that in just three of his first five starts this season.
Vogelsong (1-2, 6.23 ERA) couldn't make it to the sixth inning in his last start against the Padres, allowing a season-high six runs (five earned) on eight hits in five innings of work for his second loss of the season.
"I'm just off, man. I can't get anything really going," Vogelsong said after the start.
He'll look to get back on track Saturday against the Dodgers at AT&T Park.
Vogelsong will be up against Dodgers right-hander Matt Magill, who is making only his second Major League start.
Magill, who filled in for Stephen Fife a week ago, will start in place of Ted Lilly, who was placed on the disabled list Friday with a strained rib-cage muscle.
Magill wasn't intimidated by the bright lights of Dodger Stadium in his first Major League start, allowing just two runs on four hits in 62/3 innings for the no-decision.
"I was just amazed by his confidence and his composure and his ability to slow the game down," catcher A.J. Ellis said after the game. "He was in complete control of his mannerisms and his body and he was great. He was amazing."
Dodgers: Gonzalez scratched with neck problem
First baseman Adrian Gonzalez was a late scratch from Friday's game against the Giants with a stiff neck.
Gonzalez was injured when he collided with first-base umpire Tony Randazzo as he turned to chase a double down the right-field line in the eighth inning of Wednesday's game, although he stayed in the contest.
Dodgers manager Don Mattingly said he didn't hear anything about a problem until Friday afternoon, when Gonzalez mentioned the injury to him. Gonzalez tried to hit in the indoor batting cage and reported continued discomfort.
Giants: Abreu begins rehab stint
Infielder Tony Abreu, on the disabled list since March 22 with a left knee sprain, began a rehab assignment with Triple-A Fresno on Friday night.
"It's good to get him going on his rehab," Giants manager Bruce Bochy said. "It took longer than anybody thought. For him, he's in Spring Training."
The 28-year-old has spent parts of four years in the Major Leagues, most recently with the Kansas City Royals last year.
• The Dodgers (60-58) are the only visiting National League club to post a winning record at AT&T Park since it opened in 2000.
• Giants catcher Hector Sanchez was optioned to Triple-A Fresno on Friday.
• Buster Posey's solo shot Friday in the bottom of the ninth inning marked his first career walk-off home run.
