SCOTTSDALE, Ariz. -- Right-hander Tim Lincecum played catch on flat ground Wednesday, dispelling fears about the stiff back that forced him to skip his bullpen throwing session one day earlier.

Manager Bruce Bochy said that Lincecum likely will throw off a bullpen mound Thursday if he feels fit.

"I said this yesterday: It's pretty normal [during] Spring Training to get some stiffness in the back," Bochy said.

Right-hander Brian Wilson (throwing elbow) and left-hander Dan Runzler (left side), who are attempting to overcome injuries but have thrown freely, also are expected to throw bullpen sessions. Lincecum, Wilson and Runzler each have thrown off a bullpen mound once since workouts for pitchers and catchers began Sunday.

Huff shows up ready to regain 2010 form

SCOTTSDALE, Ariz. -- Looking fresh and fit, Aubrey Huff arrived in camp Wednesday sounding intent on looking ahead, not toward the past.

Huff didn't even feel like reviewing his offseason training regimen, which featured mostly Pilates exercises.

"All my workouts were what I did in 2010," said Huff, who excelled that year (.290, 26 home runs, 86 RBIs) before slumping last season (.246, 12, 59). "I'm coming in here in a positive mindframe and ready to go."

Huff's offseason included little or no hitting. This also repeated the pattern Huff followed as he approached the season that ended in a World Series conquest for the Giants.

"In 2010 I hardly did any swinging," Huff said. "We've got a month and a half here to get our swing right. You use the offseason mostly to get your body right."

With position players due to report to camp Thursday, one day before San Francisco's initial full-squad workout, every notable Giant except outfielder Melky Cabrera has visited the Scottsdale Stadium complex.

Whiteside regaining strength in injured elbow

SCOTTSDALE, Ariz. -- Eli Whiteside said that he has almost completely recovered from the strained right elbow that nagged him last season.

Whiteside, who faces a rigorous competition with Chris Stewart and possibly Hector Sanchez for the backup catcher's role, underwent platelet-rich plasma therapy during the offseason to help mend his elbow. On three separate occasions, Whiteside's own blood, rich with concentrated platelets, was injected into the affected area to hasten its repair.

Due to the treatments, Whiteside wasn't able to throw as much during the offseason as he typically does. But he's able to reach 120 feet with his throws, which happens to be roughly the distance between home plate and second base -- the longest peg a catcher typically will have to make.

"My arm strength isn't quite there yet," Whiteside said. "But it's getting there. It feels good. So hopefully that will continue."

With Buster Posey sidelined through most of last season, Whiteside withstood the elbow discomfort and appeared in a career-high 82 games, starting 64. He hit .197 with four home runs and 17 RBIs.
