SAN FRANCISCO -- With limited center-field and leadoff options, Giants manager Bruce Bochy said Tuesday that Aaron Rowand and Cody Ross would get the majority of starts at those positions with Andres Torres likely out for the rest of the regular season following an emergency appendectomy.

In Tuesday's series opener against the Dodgers, Rowand was in center batting eighth, while Ross hit leadoff and was in right. Entering Tuesday, Rowand had batted leadoff in five of his previous six starts, while Tuesday's game marked only the sixth time in Ross' career he has started at leadoff. The previous five times came during a two-week span in early May 2008.

"You'll see one of those two out there for the most part," Bochy said. "Right now we need experience, and these guys have been through it and know how to play and are looking forward to getting some opportunities."

Other options Bochy said he and staff discussed were September callups Eugenio Velez -- who appeared in 10 games in center for the Giants in 2009 -- and Darren Ford, as well as Opening Day right fielder Nate Schierholtz. Bochy said it was possible for Velez and Ford to get late-inning experience with the game in hand, but said Schierholtz probably wouldn't get a long look due to inexperience at the position. Entering Tuesday, all of Schierholtz's 204 career appearances as an outfielder had come in right and he also never played center in the Minors.

Sanchez plays despite knee discomfort

SAN FRANCISCO -- Freddy Sanchez was in the lineup Tuesday, but said prior to the game some fluid build-up in his surgically repaired left knee perhaps could need to be drained as soon as after the game.

After Sunday's series finale against the Padres, Sanchez was limping in the clubhouse. On Tuesday, Sanchez said the pain was better, and manager Bruce Bochy said the Giants don't have any major concern regarding the knee.

Sanchez, who had surgery in September 2009, entered Tuesday hitting .394 with five doubles, three homers and nine RBIs in his past 18 games, putting the former batting champ at .286 on the season.

Torres feeling better after surgery

SAN FRANCISCO -- Two days after undergoing an emergency appendectomy, Andres Torres was at AT&T Park, shaking hands with teammates and showing off his scar prior to Tuesday's game against the Dodgers.

"I feel better," Torres said. "Those things happen, you know?"

After experiencing soreness in his side for a couple of weeks, Torres finally went to the hospital early Sunday morning, where they took a CT scan and decided his appendix needed to be removed. Torres, who batted only 5-for-47 in his past 12 games, said, "I don't believe in excuses," but added he hadn't been feeling great during the slump.

As for his return, Torres said doctors told him it would take a few weeks, but the 32-year-old center fielder said he hoped to return sooner. As for a potential role in the playoffs, Torres said, "We just have to wait and see how I feel."

Until then, Giants manager Bruce Bochy said San Francisco has to go ahead with the assumption Torres will not be back.

"I don't think it's going to do us any good to think about when he's going to come back, so we've got to move on," Bochy said. "We've got some players, we've got some depth and we'll see now how they'll respond to playing time."

Burns' 'Baseball' follow-up focuses on Bonds

SAN FRANCISCO -- Barry Bonds is about to re-enter the public eye. Ken Burns has seen to that.

Burns, the accomplished filmmaker, has created a much-anticipated follow-up to his nine-part 1994 PBS documentary, "Baseball." It's called "The Tenth Inning" and will premiere on PBS later this month.

Burns turns historical topics into biographical ones by following the compelling storylines of individuals who enliven the subject matter. In "The Tenth Inning," he did this with Bonds, the all-time home run leader and former Giants slugger who loomed large in baseball's performance-enhancing drug controversy.

Bonds' legal issues prevented Burns from interviewing him. But Burns and his team did speak to numerous people in and around baseball about Bonds, including ex-Giants manager Felipe Alou and former shortstop Omar Vizquel.

"Barry Bonds is sort of the center narrative of this entire two-part, four-hour series that we've done," Burns said Tuesday during a promotional visit to AT&T Park. "He is the symbol, for better and for worse, of the last two decades in baseball, that I think are among the most consequential, if not the most consequential, in the history of the game."
