LOS ANGELES -- Monday's suspension of right-hander Guillermo Mota and the accompanying move, first baseman Aubrey Huff's reinstatement from the 15-day disabled list, reduced the Giants' pitching staff to 11 men, which by their standards left them lacking depth.

But manager Bruce Bochy is prepared to face the future -- at least the immediate future -- with just six relievers. Should the Giants experience one or two games in which the bullpen is depleted, they'd likely rush a reliever to the Majors and make the difficult decision of trimming a position player.

Asked if the status of the 11-man staff will be evaluated day to day, Bochy said, "I think that's pretty accurate. If we get in a situation where we think we need a pitcher, we're going to have to make a change. Right now we're going with 11 pitchers."

The Giants have multiple options if they want to summon a pitcher. Triple-A right-hander Dan Otero already has spent time with the Giants. Top prospect Heath Hembree, another right-hander, is another candidate. So is Shane Loux, who was converted from starting to relieving. And it just so happens that right-hander Brett Bochy, Bruce's son, entered Monday unscored upon in 18 innings at Double-A Richmond.

Happier Huff activated from disabled list

LOS ANGELES -- The smile on Aubrey Huff's face said it all.

Monday, the Giants activated Huff, who was diagnosed with an anxiety disorder, from the 15-day disabled list. Huff said that visits to a mental therapist helped him regain a sense of well-being that he had lacked.

"I got some things off my chest and a lot of things made sense," Huff said. "It kind of put things more in perspective. I think sometimes I put things a little too close to the heart, and a little pressure builds up. I try to put myself in check, keep my mind positive, play the game for fun and let the chips fall where they may."

Giants manager Bruce Bochy sounded pleased to welcome back Huff, who took right-hander Guillermo Mota's spot on the active roster. Mota was suspended for 100 games for testing positive for a substance in violation of MLB's Joint Drug Prevention and Treatment Program.

"I'm excited. I think Aubrey is, too," Bochy said. "He gives us an experienced bat, a guy who can hit in the heart of the order."

Huff might not be ready for that responsibility yet. He went on the disabled list with a .182 batting average, one home run and four RBIs in 12 games.

"We have to get him going," Bochy said. "I have to find a spot to put him in the game and hopefully give him an at-bat or two to get his timing down. If you get him going, he gives this club what we need and that's a guy who can drive in runs."

Huff admitted that he felt personally burdened in 2011, when he hit .246 with 12 homers and 59 RBIs after batting .290-26-86 during San Francisco's 2010 World Series-winning season.

"I want to get back to 2010," Huff said. "There was a lot of stuff on my plate last year."
