Rosario, Gaudin, Affeldt unlikely to pitch again this year

NEW YORK -- Injuries likely have ended the 2013 season prematurely for left-hander Jeremy Affeldt and right-handers Chad Gaudin and Sandy Rosario, manager Bruce Bochy said Friday.

Still bothered by the strained left groin that sidelined him, Affeldt has appeared just once since coming off the disabled list last Thursday. Carpal tunnel syndrome has prevented Gaudin from pitching since Aug. 16, and Rosario sustained a hip injury in the opener of the Mets series on Tuesday.

Bochy said the three are in the "same boat," adding, "It's doubtful they'll pitch again before the season's over."

Affeldt, who's under contract for two more years, and Rosario, who also remains under contractual control, will be back next year. Gaudin thrived both in relief and as a starter, but the nature of his injury might make the Giants wary of re-signing him.

"I think we have a sense of who he is," Bochy said. "It would be nice to get him back out there. That would mean he would be healthy and over his injury."

Lopez wants to stay with Giants, but future uncertain

NEW YORK -- Javier Lopez wants to remain with the Giants, and he knows that the Giants want him in their bullpen, but as a potential free agent, he realizes that signing him ranks no higher than third on the club's offseason to-do list, behind addressing the Hunter Pence and Tim Lincecum situations.

Lopez is concluding what might be his best overall season since he joined the Giants at the Trade Deadline in 2010. The left-handed specialist entered Friday with a streak of 17 scoreless appearances. His statistics in several categories this year are his best, including strikeout-to-walk ratio (2.92), strikeouts and walks per nine innings ratios (8.1 and 2.8, respectively), average walks and hits per inning (1.060), ERA (1.63) and opposing left-handers' batting average (.157).

Though manager Bruce Bochy isn't certain that this has been Lopez's finest season, "It's got to be right up there," he said. "He has been so consistent for us."

Lopez was encouraged when the Giants didn't ship him to another club before this year's Trade Deadline, but if he goes on the open market, he's open to irresistible offers from other clubs.

"We'll have to see how it plays out," said Lopez, who's coming off a two-year, $8.5 million deal. "The front office and coaching staff are on the same page as far as my wanting to stay here. San Francisco is a beautiful place to play, and I love playing there. I won two titles there. That always makes it easy to put them as a big favorite, obviously. But there are a lot of spots that need to be filled before they get to me."

Stewart grateful for time spent with Giants

NEW YORK -- Chris Stewart expressed gratitude toward the Giants for solidifying his Major League career.

Following his half-season with San Francisco in 2011, Stewart has spent two full years with the Yankees after spending most of his first nine professional seasons in the Minor Leagues. He has been New York's primary catcher this season, appearing in a career-high 104 games and batting .213 entering Friday's series opener.

The Giants summoned Stewart from Triple-A Fresno after Buster Posey sustained the horrific injuries to his left leg on May 25. Stewart played 67 games for the Giants, starting 51 of them, before he was traded him to the Yankees on April 4, 2012, for right-hander George Kontos.

"I think that was where I caught my break," Stewart said of his time in San Francisco. "I was kind of waiting for quite a few years in the Minor Leagues. I was hoping to get established and show what I could do on a national scene. That kind of opened the door to a bunch of other teams. I can't thank the Giants enough for giving me that opportunity. They're the ones who kind of put me in the spotlight and allowed me to show what I could do."
