SAN FRANCISCO -- Manager Bruce Bochy was walking through the concourse to the Giants clubhouse Wednesday morning when a quicker pedestrian passed him.

It was Buster Posey, injured left leg and all. As Bochy related, he told his sidelined catcher, "Jeez, you have a little hop to your step."

And for good reason. Posey will travel to the Giants' training complex in Scottsdale, Ariz., on Thursday to continue rehabilitating his leg. Head athletic trainer Dave Groeschner said that Posey should able to take swings off a batting tee by next week. Posey will intensify his range-of-motion and strengthening exercises in Arizona while gradually broadening his range of baseball drills. Catching a pitcher's bullpen throwing session remains Posey's primary short-term goal during his Arizona stint, which is scheduled to last until Nov. 1.

Groeschner expressed cautious optimism regarding Posey, who's expected to be ready for Spring Training 2012.

"He's maybe a little ahead [of schedule] or right on it," Groeschner said. "That's great and all, but we still have to get to the finish line."

Wednesday, Posey played catch for the third time since being cleared for limited baseball-related activities and, said Bochy, jogged lightly on a treadmill.

"He feels good. He's in a good frame of mind," Bochy said. "You can tell he's excited that he can turn up the baseball activities a notch. It's been a tough summer for him."

Two homers give Beltran 300 for career

SAN FRANCISCO -- Carlos Beltran became the ninth switch-hitter to reach the 300-homer plateau when he hit his second home run of the game in Wednesday's sixth inning against the San Diego Padres.

Beltran connected off Padres starter Mat Latos for No. 299 with two outs in the first inning and repeated the feat with one out in the sixth, launching the 59th "splash hit" into McCovey Cove. The Giants went on to beat the Padres, 3-1.

Beltran at once downplayed and celebrated his accomplishment. Like most athletes, he said that he didn't focus on statistics. But he was clearly satisfied.

"It's a lot for me, actually," said Beltran, 34. "Thank God for that. I've been able to be in this game for a long time. Three hundred -- for a guy from Manati, Puerto Rico, a small town, it's good."

The other switch-hitters to precede Beltran to the 300-homer mark were Mickey Mantle (536), Eddie Murray (504), Chipper Jones (453), Lance Berkman (357), Chili Davis (350), Reggie Smith (314), Mark Teixeira (312) and Ruben Sierra (306).

"Every time you accomplish something that only a few people have accomplished, it's a great feeling," Beltran said.

Beltran recorded his 30th career multiple-homer game. It also was his third of the year and his first since being traded to the Giants from the Mets on July 27.

Worth noting

• Giants manager Bruce Bochy indicated Wednesday that closer Brian Wilson remains on course to resume pitching. Wilson, who has been sidelined by elbow inflammation since Aug. 16, played light catch and will pitch his second session of live batting practice to hitters Thursday at Denver's Coors Field.

• Left-hander Jonathan Sanchez threw on flat ground for the second day in a row and will head for the Giants' training complex at Scottsdale, Ariz., on Thursday to continue rehabilitating his sprained left ankle. Sanchez, who hasn't pitched since Aug. 16, hopes to make a relief appearance before the season ends.

• Right fielder Nate Schierholtz also is bound for the Arizona complex to mend the hairline fracture in his right foot further. Schierholtz said that he expects to be able to take batting practice during the Giants' season-ending home series Sept. 26-28 against Colorado. Moreover, Bochy did not rule out the possibility of Schierholtz playing briefly if he's physically fit.
