"Throwing, I have no problem doing," Huff said. "Running, I probably have to back off because the quad is a little tight, but that's how every strain goes. It's just a matter of maintaining and being smart. As long as I can throw, cover first base and field a bunt, that's all I need to be doing."
Huff threw three scoreless innings in a rehab outing for Triple-A Fresno last Thursday, but has not appeared in a game for the Giants since April 21.
