Giants left-hander Jonathan Sanchez might be done for the season with a left ankle sprain that hasn't improved.
"He's still not making the progress we'd hoped. He hasn't thrown at all. He's a ways away," manager Bruce Bochy said. "The way it's going, it could be a close call between he and Buster (Posey)."
Jonathan Sanchez last threw Aug. 19 at Houston to see if he could start two days later, but he didn't respond.
