SAN DIEGO -- Second baseman Freddy Sanchez, who remains doggedly determined to rejoin the Giants, is continuing to work toward full health at the club's training complex in Scottsdale, Ariz.

Sanchez, who has endured several setbacks in his attempt to recover from a dislocated right shoulder, is throwing at a 105-foot distance and hitting off a tee, Giants manager Bruce Bochy said Thursday.

"At least he's doing baseball activities again. That's promising," Bochy said.

Also, left-hander Dan Runzler, who has been bothered by a left latissimus dorsi strain, will begin an injury rehabilitation assignment with Class A San Jose on Friday. Runzler will start that night, but will be limited to one inning or approximately 20 pitches.

Always hoping for more bullpen depth, Bochy said, "It'd be nice to have him available, if needed. We're hoping to get him back to where he was."

Melky fine after exiting with hamstring issue

SAN DIEGO -- Giants left fielder Melky Cabrera felt tightness in his right hamstring after stealing second base in the seventh inning of Thursday's 8-3 victory over the Padres, prompting manager Bruce Bochy to remove him from the game one inning later.

"We're just being cautious," Bochy said, indicating that Cabrera's ailment isn't serious.

Cabrera, who's batting .364 to lead the National League, went 1-for-4 and scored twice.

After Panda returns, Arias to still see action

SAN DIEGO -- Joaquin Arias will cease to be the Giants' everyday third baseman when Pablo Sandoval makes his anticipated return from the disabled list next week. But Arias' versatility should enable him to stay busy.

Arias' ability to play second base and shortstop, as well as third base, should guarantee him at least occasional starts once Sandoval's comeback from a fractured left hamate bone puts him on the bench.

"We'll be able to give guys more rest," Giants manager Bruce Bochy said.

Already this season, Arias has started twice at second base and six times at shortstop.

Bochy reiterated that he wants to give shortstop Brandon Crawford an occasional break. Crawford has started 51 of San Francisco's 58 games. And though Ryan Theriot has evolved into a regular, Bochy might feel compelled to rest the second baseman once in a while as a preventive measure to keep his healed right elbow sound.

Giants Wives/Community Fund to hold auction

SAN DIEGO -- The annual Giants Wives/Community Fund auction will be held during and after Saturday's game against the Texas Rangers at AT&T Park.

Baskets filled with the favorite items of several players -- restaurant certificates, snacks, movies, books -- will be made available for bidding from 11 a.m. through the fourth inning at the Community Clubhouse on the Promenade Level behind home plate. Among the Giants who have put together goodie baskets are Jeremy Affeldt, Brandon Belt, Madison Bumgarner, Brandon Crawford, Aubrey Huff, Javier Lopez, Angel Pagan, Buster Posey, Nate Schierholtz and Ryan Vogelsong.

Numerous other prizes will be available in the postgame live auction staged atop the Giants dugout, such as opportunities to meet broadcasters Mike Krukow and Duane Kuiper, general manager Brian Sabean, manager Bruce Bochy and former first baseman J.T. Snow. A pitching lesson from All-Star right-hander Matt Cain also will be among the experiences up for auction.

Proceeds benefit the Giants Community Fund; the George Mark Children's House, which is a hospice home for children; and bullpen coach Mark Gardner's Step to the Plate Foundation.
