LOS ANGELES -- Giants closer Brian Wilson, recovering from Tommy John elbow surgery, will resume throwing in October.

This was among the subjects Wilson discussed with manager Bruce Bochy when the right-hander visited Dodger Stadium on Tuesday.

"I talked to Willie quite a bit yesterday," Bochy said. "It seems like he's in a good place mentally."

Bochy added jokingly, "The beard did not took healthy."

Bochy indicated that Wilson, who underwent surgery April 19, won't be ready to participate fully in workouts when Spring Training begins. But, as Bochy said, "There's no need to get ready for Spring Training," suggesting that Wilson will approach his rehabilitation and recovery in gradual fashion.

Posey scratched with ailing hamstring

LOS ANGELES -- Tightness in catcher Buster Posey's right hamstring forced the Giants to scratch him from the lineup for Wednesday night's series finale against the Los Angeles Dodgers, though he's not considered seriously injured.

Manager Bruce Bochy didn't rule out using Posey late in the game as a pinch-hitter or, in an emergency, on defense, as long as the Giants' leading hitter responded to treatment. Posey's playing status is day to day.

Bochy denied that the Giants' victories in the series' first two games made resting Posey less burdensome.

"It really wouldn't matter if we lost the first two. He wouldn't play," Bochy said.

Bochy said that Posey's discomfort increased gradually throughout Tuesday night's 4-1 victory over Los Angeles. Posey, who went 1-for-3 with a two-run single, left the game after his final at-bat in the seventh inning. He and the Giants initially believed that he'd be able to play Wednesday, but he still didn't feel right after his leg was examined.

Posey, who was sidelined for the final four months of the 2011 season after sustaining multiple left leg injuries in a home-plate collision, entered Wednesday ranked among the National League leaders in batting average (third, .327), on-base percentage (third, .403), RBIs (tied for fourth, 79), batting average with runners in scoring position (fifth, .339) and slugging percentage (fifth, .538). He appeared in 112 of San Francisco's first 123 games, starting 87 at catcher and 18 at first base.

Penny's rehab moving up to Class A

LOS ANGELES -- Right-hander Brad Penny will continue his recovery from shoulder problems with Class A San Jose beginning Thursday, the Giants' farm club announced.

Penny, 34, pitched an inning for the Rookie-level Arizona League Giants on Tuesday. He allowed three runs (two earned) and two hits.

Penny was 0-1 with a 6.86 ERA in 15 relief appearances for San Francisco -- his first extended stint in the bullpen in 13 Major League seasons -- before he went on the disabled list Aug. 14 with a right shoulder impingement.
