Pagan could start rehab assignment soon

SAN FRANCISCO -- The training room is the only place inside the Giants' clubhouse that's been more crowded in the last 24 hours than the space outside Jake Peavy's locker stall. Manager Bruce Bochy discussed his handful of unavailable players before Sunday night's game against the Dodgers.

• General manager Brian Sabean said Angel Pagan (back strain) could return to the Giants on their next road trip on his radio show last week. Bochy said Pagan's condition has improved and he's close to beginning a rehab assignment.

Bochy said Pagan is running and taking live batting practice. Word is expected Monday or Tuesday on when and where he'll begin a rehab assignment.

"At that point [Monday or Tuesday], he could be really close, if not ready, to start playing some games," Bochy said.

There is no target date for Pagan's return, though. He last played June 14.

Brandon Belt was placed on the seven-day disabled list with a concussion Monday, retroactive to July 20, making him eligible to return Sunday, but Bochy said the first baseman wouldn't be returning.

A doctor was scheduled to re-evaluate Belt before Sunday night's game; he has not been cleared to resume baseball activities. Bochy said Belt started showing signs of progress Friday, but it's "going to be a few more days" until he likely returns since he "still feels it a little bit."

• Bochy had noting new to share on Matt Cain, who was sent to the disabled list Monday with right elbow inflammation.

On Saturday, Sabean said Cain's condition has remained stagnant despite his rehab regimen, which led to Sabean intensifying trade talks with the Red Sox for Peavy. Sabean was non-committal when asked if Cain would return at all in 2014.

"The longer [Cain] goes in this dormant stage, the more we're probably going to have to seek second opinions and more diagnostics, thus the timeline gets stretched out," Sabean said Saturday. "There may be a worst case. We haven't gotten to that point yet."

• Catcher Hector Sanchez was placed on the seven-day disabled list with a concussion Saturday after taking a vicious foul tip to the mask in Friday night's game. Like is the case with Belt, Bochy doesn't anticipate Sanchez returning after his weeklong stint on the DL ends.

Sanchez was scheduled to be re-evaluated along with Belt before Sunday night's game; he has not yet been cleared to resume baseball activity.

Marco Scutaro's long-awaited return to the Giants was brief, and Bochy anticipates Scutaro being used sparingly if and when he returns from the 15-day disabled list with lower back problems.

"It's already been proven, I guess you could say, that it's going to be hard to do, unless he really turns the corner," Bochy said when asked if Scutaro would resume duties as the starting second baseman upon his return.

"We're just trying to get him healthy enough to where he can help us two to three days a week, but it flared up pretty good on him."
