SAN FRANCISCO -- Jonathan Sanchez is likely bound for the Giants' training complex in Scottsdale, Ariz., to continue rehabilitating his sprained left ankle. But the left-hander still wants to pitch again this season.

Manager Bruce Bochy said that Sanchez, who hurt himself Aug. 16 at Atlanta, probably will head for Arizona on Wednesday along with catcher Buster Posey (left leg) when the rest of the team leaves for a three-city, 10-game trip. Sanchez's immediate future could be determined by how his ankle responds to a scheduled throwing session on flat ground Tuesday.

"It wasn't getting better, so I took a week off without throwing," said Sanchez, who began the season as San Francisco's No. 2 starter. "I want to finish the season healthy."

Sanchez admitted that if he returned, he'd have to perform in relief, since he doesn't have time to build up the stamina to start.

Posey will keep working on regaining strength and range of motion in his leg until he's able to catch pitchers' bullpen sessions.

Wilson wants 2011 return, faces hitters

SAN FRANCISCO -- Remaining intent on pitching competitively in 2011, right-hander Brian Wilson flung 19 pitches to hitters off the AT&T Park mound Monday as he continued his recovery from inflammation in his throwing elbow.

Giants manager Bruce Bochy said he felt "more optimistic" that Wilson, who hasn't pitched since Aug. 15, will be able to pitch before the Sept. 28 regular-season finale against Colorado.

Wilson apparently shares Bochy's sentiment.

"He would like to get back out there before the season's over. That's why he's continuing to work hard," Bochy said. "He could very easily say, 'I'm going to shut it down,' but that's not him. He wants to get back out there and help the ballclub. Though we know we're hanging by a thread, he hasn't stopped trying to get back. He's been relentless with his rehab and his workouts. That's what you appreciate about Willie."

Pitching before the season ends also might improve Wilson's outlook as he enters the offseason.

"It probably would give him a little sense of relief and peace of mind," Bochy said.

Bochy said that Wilson likely will rest for two days before embarking upon his next plan of action. The Giants closer still ranked sixth entering Monday among National League relievers with 35 saves in 40 opportunities.

Giants want to see Zito in action

SAN FRANCISCO -- Like Jonathan Sanchez, left-hander Barry Zito appears unlikely to start again this season. But Bochy indicated that Zito, who was activated from the disabled list Sunday, soon will receive a chance to pitch.

"We'd like to see where he's at," Bochy said.

Bochy didn't completely rule out giving Zito a start, though he indicated that the chances of such an event were minimal in the 15 games following Monday.

"I can't tell you when or where, but it's possible," Bochy said.

Worth noting

• Bochy acknowledged that third baseman Pablo Sandoval has regained some of the weight he lost before this season, when he shed an estimated 40 pounds to 240. But Bochy quickly added that Sandoval's in much better shape than he was last year, when his playing time dwindled toward the end of the season and he was benched in the World Series except for a one-game stint as a designated hitter. "Overall, it's been good," Bochy said of Sandoval's self-maintenance.

• Catcher Chris Stewart hasn't played since he hurt his right ankle last Friday, an injury which he classified as a "strain." Stewart has been undergoing treatment but said that he didn't know when he might resume playing.
