"Giants left-hander Barry Zito was helped off the field by trainers after sustaining an apparent injury to his right foot during a rehab start at Triple-A Fresno on Saturday night.

Zito is on the disabled list for the second time this season because of the foot, which he sprained in April while fielding his position. The $126 million left-hander has struggled in nine starts for the Giants this season, going 3-4 with a 5.62 ERA, leading some to wonder if his second D.L. stint was legitimate."
